Atomic Lies
By RICHARD MONASTERSKY
With his shoulders hunched and a cigarette
in hand, Victor
Ninov paces the edge of San Francisco Bay. Four
miles away and
600 feet up, his former workplace basks in the
morning sun,
set off amid stands of eucalyptus and pine. The
lab in the
Berkeley Hills occupies a vaunted place in the
annals of
physics, and Mr. Ninov had been a rising star
there. But now
he must view it from a distance, walking through
a park built
on this city's former dump.
Just a short time ago, the nuclear physicist was
on his way to
winning the field's highest honors, as well as
putting his
stamp on the periodic table of the elements. In
1999, he
co-directed an atom-smashing experiment at the
Lawrence
Berkeley National Laboratory that created two
new elements,
Nos. 118 and 116, the heaviest yet discovered.
The result made
Mr. Ninov a physics sensation. He went on tour,
describing the
experiment in lectures across the United States,
Europe, and
Australia.
The 43-year-old Bulgarian seemed the ideal scientist,
says a
former colleague, Albert Ghiorso, who has co-discovered
more
elements than anyone in history. "Victor could
do anything
mechanically. He knows about electronics down
to the finest
details. He knows all about experimental nuclear
physics. He
knows theoretical aspects of all this. And he's
a violinist,"
says the 87-year-old Mr. Ghiorso.
"He's just a fabulous guy. He has lots of energy
and works
hard."
But Mr. Ninov tumbled on his rise to the top.
Other
laboratories tried and failed to repeat the experiment,
and
even Mr. Ninov's team could not duplicate its
own results. To
great embarrassment, the researchers at Lawrence
Berkeley -- a
federal facility managed by the University of
California --
had to retract the discovery last year. Following
an
investigation, laboratory officials eventually
determined that
Mr. Ninov had faked the data. They quietly fired
him in May.
The case has crippled more than just one man's
career. It has
also toppled his research team at Lawrence Berkeley,
which
spawned the entire element-hunting enterprise
in the 1930s and
changed the world forever by discovering plutonium,
as well as
a suite of medical isotopes that help millions
of patients
each year. The scientists there are still reeling.
"The whole group has been in shambles ever since
it happened,"
says Peggy McMahan, research coordinator at the
Lawrence
Berkeley cyclotron where Mr. Ninov conducted his
experiments.
At the center of the maelstrom, Mr. Ninov remains
an enigmatic
character who swears that he is innocent and raises
the most
perplexing question of all, one that haunts his
colleagues
across two continents: Why? Why fake a scientific
result
knowing that others would eventually discover
the misconduct
while trying to duplicate the experiment?
'Perfectly Free'
For a man accused of one of the worst types of
crime known in
science, Mr. Ninov laughs easily and often during
a walk
around the Berkeley Marina, where he keeps his
38-foot
sailboat. Partly out of a love for sailing and
also because of
the high rents in the Bay Area, Mr. Ninov lived
aboard his
cramped boat while working at the laboratory.
On weekends, he
would commute to his house in Stockton, Calif.,
where his
wife, Caroline Cox, is a history professor at
the University
of the Pacific.
Mr. Ninov has a slender build, pale-blue eyes,
and curly brown
hair starting to gray at the temples. He is deeply
tanned,
having just returned from a 3,500-mile trip on
a friend's
sailboat that went from San Francisco to the Marquesas
Islands, in the South Pacific. After 15 years
of struggling on
experiments with little time off for long trips,
"I am
perfectly free. I am enjoying a little bit of
a vacation," he
says in Slavic-tinged English and a voice cured
by thousands
of Camel Lights.
Talking about his past, Mr. Ninov is guarded with
dates and
details, some of which remain painful. While still
a boy in
"the early 1970s," he and his family fled Communist
Bulgaria
and settled in what was then West Germany, moving
several
times. His father subsequently disappeared in
the mountains of
Bulgaria, and his body was found six months later,
the
circumstances of his death unknown.
As an undergraduate and graduate student in Germany,
Victor
Ninov studied physics at the Technical University
in
Darmstadt, and his career began a steep ascent.
For his thesis
and then a postdoctoral fellowship, Mr. Ninov
worked at
Darmstadt's prestigious Institute for Heavy Ion
Research,
known universally as GSI for its German name.
Researchers there had already discovered three
new elements,
Nos. 107 through 109, in the early 1980s, and
the wunderkind
joined the group as it was running confirmation
experiments.
In a short time, Mr. Ninov distinguished himself
for his
knowledge of computers and ability to build technical
instruments. "We thought he had an excellent scientific
career
in front of him," says Sigurd Hofmann, a professor
of nuclear
physics at the University of Frankfurt and leader
of the
heavy-element group at GSI. "He was a very good
physicist in
many different fields of physics." The young scientist
also
impressed others with his cultured interests.
An aficionado of
classical music, he speaks Bulgarian, English,
French, German,
and passable Russian.
Because of his computer skills, Mr. Ninov was
given sole
control over the analysis program in the GSI experiment.
He
would later reprise the role at Lawrence Berkeley,
as the only
member of the team who knew how to run the critical
computer
program. Both groups would come to regret placing
him in that
position.
How to Make an Element
The recipe for cooking up a new element requires
a bit of
atomic magic, something that medieval alchemists
spent
centuries seeking as they strove to transmute
lead into gold.
In modern experiments, however, nuclear researchers
change
lead and other relatively ordinary matter into
something far
rarer and dearer than gold.
The instrument that enables such transformations
was born here
in 1931, when Ernest O. Lawrence, for whom the
lab is named,
created a device called a cyclotron, which earned
the young
professor a Nobel Prize eight years later. Lawrence
dubbed his
machine the "proton merry-go-round," an apt term
for a device
that accelerates atomic nuclei by whipping them
around in
circles. Once revved up to high energies, the
charged
particles then fly out of the cyclotron and slam
into a target
of ordinary matter. The magic happens when a projectile
nucleus hits a target nucleus just right, with
so much energy
that the two fuse, creating a bigger element.
The result is simple arithmetic. Element No. 1,
hydrogen, has
one proton. Uranium has 92. When the two fuse,
they produce an
artificial element with 93 protons, hence an atomic
number of
93.
In 1940, Lawrence's lab -- then part of the University
of
California at Berkeley -- used a cyclotron to
create that very
element and the next one, which they named neptunium
and
plutonium. Over the next 40 years, researchers
here discovered
12 more elements, more than any other institution.
By the 1980s, though, the laboratory's once-brilliant
luster
had dulled. The science that Lawrence started
had grown, and
so had the accelerators, reaching a scale that
couldn't fit
easily into the Berkeley Hills.
The United States chose to build its premier facility,
the
Fermi National Accelerator Laboratory, in flat
fields west of
Chicago, where its main accelerator is 1.3 miles
across. Other
big accelerators sprang up near Stanford University
and at
Brookhaven National Laboratory, in New York. Meanwhile,
the
California city that had helped launch the atomic
age became a
nuclear-free zone, and activists here began to
hamper the
lab's efforts to conduct experiments with significant
amounts
of radiation.
As the 1990s began, the Department of Energy and
other federal
agencies were financing Lawrence Berkeley primarily
to do work
in materials science, biology, nuclear medicine,
and other
applied fields, with relatively little going toward
nuclear
physics. GSI, in Germany, had taken a leading
role in making
elements, as had a group at the Joint Institute
for Nuclear
Research, in Dubna, Russia. At Berkeley, the element
hunters
contented themselves to work with a cyclotron
built in 1961.
The device's control room has such aged light
bulbs, meters,
and dials that students say it looks like the
set of the
original Star Trek.
Island of Stability
Despite its difficulties, Lawrence Berkeley was
still one of
the top three labs in the world for making new
elements. All
three competitors were eagerly seeking the prized
"island of
stability," atoms with special combinations of
protons and
neutrons that persist for a long time -- seconds,
weeks,
possibly millennia -- before falling apart.
With such relatively long half-lives, those isotopes
could
prove useful in treating cancer, creating medical
diagnostic
procedures, or even producing nuclear weapons.
In 1996, Lawrence Berkeley hired Mr. Ninov, by
now a
world-class expert, as part of an effort to search
for that
fabled island of stability. The team specifically
wanted help
building an instrument, called a gas-filled separator,
that
Mr. Ninov had constructed in Germany.
Once settled here, he joined a nuclear chemist
named Kenneth
E. Gregorich on the project. Tall and bald, with
deep-set eyes
and a prominent nose, Mr. Gregorich had practically
grown up
at the lab, having done his doctoral work under
Glenn T.
Seaborg, the Nobel-winning chemist who co-discovered
plutonium
and nine other elements here. Mr. Gregorich worked
with Mr.
Ninov every day for five years. When he describes
their work,
he wears the pained expression of a man whose
spouse has
cheated on him.
The colleagues spent their first two years piecing
together
the separator, which sits in a bunkerlike room
that adjoins
the massive cyclotron. The cyclotron itself remains
walled
off, hidden behind six feet of concrete and battleship
steel
to protect researchers from the deadly neutrons
generated
inside. A series of pipes from the cyclotron funnels
a
trillion nuclei a second into a target and then
through the
gas-filled separator.
At the lab, the Berkeley Gas Separator goes by
the initials
BGS, and it does exactly what its name implies.
As the
cyclotron beam hits the target, billions of particles
fly
right through without touching anything and billions
more
barely graze the target atoms or collide in unwanted
ways.
"This is a big machine to get rid of all the garbage
and send
only the interesting atoms to the detectors,"
says Mr.
Gregorich.
The machine turned out to be a Frankenstein, constructed
from
scavenged parts. Lawrence Berkeley couldn't make
the lead
targets for its first experiment, so the team
borrowed them
from GSI, as well as detectors and the same data-analysis
program that Mr. Ninov had used in finding Elements
110 and
112. He jokes that whenever people traveled from
Darmstadt to
Berkeley, they packed parts for the separator
in their
luggage.
When he and Mr. Gregorich were finishing the device,
in 1999,
they planned to go slowly, running a range of
experiments to
test the separator, improve its performance, and
ready it for
more-important work.
But a theorist stepped in and waylaid those careful
plans.
Robert Smolanczuk, a Fulbright fellow at Lawrence
Berkeley
from the Soltan Institute for Nuclear Studies,
in Warsaw, had
made some wild calculations about superheavy elements.
In all the work done to that point, researchers
had found it
progressively tougher to produce bigger elements
by fusing a
projectile and a target. For each step upward
in atomic
number, the chances of the two fusing dropped
considerably,
meaning that an experiment would have to run for
longer at
higher energies in order to create the desired
element.
Mr. Smolanczuk's calculations, however, suggested
that Element
118 would be relatively easy to fashion by bombarding
Element
82, lead, with Element 36, krypton. As fathers
of the new
separator, Mr. Ninov and Mr. Gregorich didn't
want to push
their progeny too fast, but other team members
persuaded them
to test Mr. Smolanczuk's theory. So they bypassed
all their
plans and aimed straight for Element 118 when
they had some
precious "beam time," in April 1999. With several
different
groups vying to use the accelerator, Mr. Ninov
and Mr.
Gregorich had only limited access to the cyclotron
beam.
Neither scientist believed Mr. Smolanczuk's theory.
"We didn't
know how many orders of magnitude he was wrong,"
recalls Mr.
Ninov, "but we said, 'OK, we can measure at least
to a certain
level.' Of course, we didn't expect to see anything
at that
time, and then suddenly it happened."
'An Event'
That it was "an event," in the lingo of the lab.
Mr. Ninov,
who was analyzing the data, says he saw signs
that an atom had
hit the detector and had immediately shed a string
of six
alpha particles -- nuclei containing two protons
and two
neutrons -- all in the same location. That decay
chain was
exactly what the researchers were seeking but
had not expected
to find: Element 118 lodging itself in the detector,
then
decaying to Element 116 by giving off two protons,
then to
Element 114, and so on down the line. In one instant,
the team
had apparently discovered two new elements, 118
and 116.
Mr. Ninov was the only one who knew about the
data, and at
first he questioned the results, he recalls. "This
was our
maiden voyage. I wasn't confident that our programs
were
debugged, that our electronics were perfectly
debugged, that
the separator was perfectly debugged."
Soon Mr. Ninov's analyses revealed another event,
and he told
Mr. Ghiorso, the most experienced member of the
team. But the
younger scientist said nothing to his other colleagues
for two
days, a fact that struck Mr. Ghiorso as particularly
odd. "I
felt I had to keep it to myself because it was
up to him. Why
did he pick me out to tell?" Mr. Ghiorso wonders
now. That's
how many people at the lab speak today, questioning
every
detail of what happened, looking for clues to
explain Mr.
Ninov's actions.
Because of his previous work in Germany, Mr. Ninov
played a
pivotal role in the Lawrence Berkeley experiments.
He was the
only one to deal with the original data, which
came from the
detectors in binary form and were stored on magnetic
tape. Mr.
Ninov ran a computer-analysis program that converted
the
binary files into text files of words and numbers
for the rest
of the team to interpret. In 1999, no one else
knew how to use
that program, so they relied on Mr. Ninov to supply
the
results.
When the physicist eventually showed the team
his analysis of
the data, everyone reacted with shock. The group
still wasn't
sure it had a real detection, so it examined Mr.
Ninov's
results several times. "It's always a nightmare
in the
heavy-element research, when you're picking a
stick out of the
hay," says Mr. Ninov. "You're thinking you've
thought about
everything, but there is for sure something you
didn't think
about."
As always in cutting-edge science, the researchers
worried
that competitors might beat them to the discovery.
Three
months earlier, Dubna had reported producing Element
114,
which fit squarely in the island of stability,
with a
half-life of 30 seconds. GSI was certainly capable
of doing
the same krypton-and-lead experiment. After all,
it had
provided many of the parts for the gas separator.
Nonetheless, the Lawrence Berkeley team played
it cautiously,
choosing to run the experiment again after improving
the
separator. Using beam time scheduled for a different
study,
the researchers tried the 118 experiment once
more. Mr.
Ninov's analysis revealed another event that was
not
spectacular but was enough to convince them that
they had a
real, reproducible discovery.
What's more, the decay sequence agreed particularly
well with
Mr. Smolanczuk's calculations. The concordance
of theory and
experiment, Mr. Ghiorso recalls, led Mr. Ninov
to exclaim,
"Robert must talk to God."
The researchers quickly wrote up their findings
and submitted
them to Physical Review Letters, the field's premier
journal.
Their paper, "Observation of Superheavy Nuclei
Produced in the
Reaction of 86Kr with 208Pb," appeared in the
August 9, 1999,
issue.
After decades of losing out to other labs, the
element hunters
at Lawrence Berkeley again made headlines. "Berkeley
Crew Bags
Element 118," proclaimed Science magazine. "Team
Adds 2
Elusive Elements to the Periodic Table," reported
The New York
Times.
Mr. Ninov enjoyed the fruits of the success, says
Mr. Hofmann,
the leader of the GSI group and Mr. Ninov's former
colleague.
"Victor became very famous that year. He was invited
to many
talks. There was much excitement. We immediately
started to
repeat this experiment in the summer of 1999."
Critical Mass of Questions
That's when the troubles started. In three weeks
of time on
its own cyclotron, the GSI team did not detect
any events of
118. Nor did groups in France or Japan. The laboratories
all
have different setups, so Mr. Hofmann, Mr. Gregorich,
and Mr.
Ninov agreed that the best approach would be to
repeat the
experiment at Lawrence Berkeley, and the team
did so in 2000.
Again, nothing appeared.
The researchers thought that statistical variations
might
explain the discrepancy: Shooting a beam at a
target is a
random process, much like dealing a shuffled deck
of cards. So
a few atoms of 118 might appear in one experiment
and then
none in another, just as a poker player might
rarely end up
with all the aces in his hand, purely by chance.
But Lawrence Berkeley officials were growing nervous.
Perhaps
a computer program had played tricks on the research
team, or
some other problem had escaped its attention.
I-Yang Lee, head
of low-energy research on the cyclotron, set up
a committee of
three staff members to investigate, and they made
several
recommendations to improve on the original experiment.
One
suggestion was to have several people independently
analyze
the raw data.
In April 2001, Mr. Gregorich and Mr. Ninov again
got some beam
time to retry the experiment. At first, it seemed
a success.
Mr. Ninov reported that the detector had picked
up a decay
chain for 118.
But the hope soon evaporated. Another team member,
Walter
Loveland, a professor of chemistry at Oregon State
University,
analyzed the new data and found no evidence of
an event.
Several other people, including Mr. Ninov, also
tried and
struck out.
In the meantime, some of the researchers finally
looked back
at the 1999 experiment. They were shocked to find
that there
were no events in the original data file.
It seemed there had never been any evidence for
the element.
No one could make sense of the situation. The
three events
were in the processed text file that several researchers
had
examined, but not in the original binary one.
Most of the scientists figured that a bug in the
processing
program had somehow escaped Mr. Ninov's attention
and created
the illusion of an event. Mr. Gregorich and his
colleagues
issued a press release and told researchers at
other
laboratories to disregard the claim for 118. At
the same time,
the team submitted a letter to Physical Review
Letters in July
2001 retracting its original finding.
In one short paragraph that offered few details,
the letter
stated simply that the experiment had not detected
Element 118
in 1999. To the rest of the world, the whole affair
looked
like a simple mistake.
But there was much more going on behind the scenes.
Mr. Ninov
stood by the original finding and refused to sign
the
retraction letter, delaying its publication until
this past
July. Meanwhile, the laboratory appointed a second
internal
committee -- made up of computer experts -- to
look into the
discrepancy. That group determined that there
was nothing
wrong with the analysis program. The only plausible
theory was
that someone had inserted false data into the
text file, and
Mr. Ninov was the only person to have worked with
the original
data.
The lab placed Mr. Ninov on leave with pay in
November 2001,
while a committee led by Rochus E. Vogt, a professor
of
physics emeritus at the California Institute of
Technology,
investigated the matter. The committee issued
its confidential
report in late March, and the lab fired Mr. Ninov
in May.
Only on June 25 did the laboratory's director,
Charles V.
Shank, tell all employees about the scientific
fraud that the
review committee determined had taken place. He
declined to
name the perpetrator, because Mr. Ninov had filed
a grievance
against the lab for unfair dismissal. Mr. Shank
also
criticized Mr. Gregorich's team for failing to
make the most
elementary checks on the data.
Missing Elements
Meanwhile, more pieces of the puzzle were emerging
across the
Atlantic at GSI. In December 2001, Mr. Hofmann
and his
colleagues went back to their original data tapes
from 1996
while writing up a paper on Element 112. The experiment
that
year had identified two decay chains from Element
112, but the
GSI team could find only the second one in the
binary file.
The first one was missing. It appeared only in
the text file
that Mr. Ninov had produced from the primary data.
The German scientists then examined every decay
chain recorded
from 1994 to 1996. They found one more false event
-- the
second sighting of Element 110, recorded in November
1994.
Mr. Hofmann says the evidence points squarely
at Mr. Ninov.
"He was the only one who was in charge. I got
the data from
him personally in a printed version on paper,
which I still
have in my folders. And if somebody else had manipulated
these
data, he certainly would have realized that they
were not his
data files."
The evidence, however, doesn't explain why a promising
scientist would decide to fabricate data. "This
is completely
not understandable," says Mr. Hofmann. "Especially
in our
case. For 110, we already had one decay chain.
In 112, he
faked the first decay chain, but we measured another
good one.
He could be honest. There was no need to keep
this wrong decay
chain. We could only explain it as a bad joke.
From our
results, it was completely useless to fake data
because there
were good ones."
At Berkeley, researchers are similarly perplexed.
They say Mr.
Ninov must have known that he would get caught
eventually,
when other labs tried to duplicate the finding.
"It's
unbelievable that anyone would do this sort of
thing," says
Mr. Lee. "There was absolutely no need for him
to do this," he
adds, noting that Mr. Ninov already had made prominent
discoveries. "His career did not depend on this."
Maybe not his career, but possibly the success
of the
experiment. Mr. Ghiorso wonders whether Mr. Ninov
was buying
time for the team, inserting false events so that
the lab
would let the experiment run longer and provide
the
opportunity to catch some real decay chains. "I'm
just
speculating," says Mr. Ghiorso, "that he 'knew'
that we would
find it sooner or later, just as they had in Germany.
He was
just anticipating, knowing that it would be confirmed,"
which
never happened.
For his part, Mr. Ninov maintains his innocence.
"I'm the
scapegoat. I don't accept the accusation of fabricating
the
data," he says, arguing that the charges don't
add up.
"They're saying I'm smart enough to run a complicated
experiment, but I'm dumb enough not to fake data
properly. And
then there's the lack of motivation. Why shall
I ruin my life
for two or three events? It's simply not worth
it."
One possibility, he says, is that he was set up
to hide an
unintentional error by the team. Suppose some
stray bit of
electronic noise had confused the computer program
by
masquerading as a real decay chain. If that's
the case,
somebody discovered the error long after the team
had made its
stunning claim and then felt embarrassed enough
to make the
mistake look like fraud.
To do that, the person must have gone into the
original binary
files to remove the faulty data that had fooled
everyone.
Without offering any names, he hints that somebody
altered the
files to focus suspicion on him. The perpetrator
must then
have pulled the same stunt in the German data
files to
solidify the case. "I do know people that are
affiliated with
LBL as well as at the GSI," says Mr. Ninov.
The investigators assembled by Lawrence Berkeley,
however,
rejected Mr. Ninov's theory because it doesn't
accord with the
dates and times of key computer files. What's
more, he was the
only team member who knew how to use the data-analysis
program. "We find clear and convincing evidence
that Victor
Ninov was responsible for the fabrication and
that he engaged
in scientific misconduct," the group concluded
in its report,
released this month.
Mr. Ninov says he is now trying to move on. Standing
at the
marina in Berkeley, looking out toward the Pacific
Ocean, he
says, "I don't have the financial means to go
to court. And
another thing, since last year was not one of
my pleasant
ones, I would rather regroup everything and start
from scratch
than continue living with the permanent psychological
pressure."
In some ways, he seems better off than the colleagues
he left
behind. The affair "killed the superheavy-element
program at
Berkeley, period. Nobody is going to do it," says
Mr. Ghiorso,
whom the team had considered honoring by naming
Element 118
"Ghiorsium." Others at the lab don't accept such
a dire
prediction, but they admit that they have a difficult
path
ahead.
The group caught some harsh criticism over the
affair, and Mr.
Gregorich is still irate that the laboratory director
chided
his team for failing to check critical data. "That's
just
wrong," he says. "There were plenty of checks.
That statement
pissed me off."
Perhaps somebody should have been analyzing the
data alongside
Mr. Ninov. But when that is suggested to Mr. Gregorich,
he
replies angrily, "I had a world-recognized expert
that we
hired and was doing that job."
Laboratory officials maintain that several people
should have
been involved in the essential step of data analysis,
but
other scientists say even that safeguard cannot
always thwart
fraud.
At some point, scientific researchers have to
trust their
colleagues, says Denis L. Rousseau, who has investigated
several cases of fraud and self-deception in science.
A
professor and chairman of the department of physiology
and
biophysics at Yeshiva University's Albert Einstein
College of
Medicine, Mr. Rousseau says that "in science,
we always depend
on the integrity of our co-workers. When that
breaks down,
it's very difficult to correct for that."
The system has a built-in protection, however,
in the
fundamental rule that investigators must try to
reproduce
interesting findings. "It isn't sexy," says Oregon
State's Mr.
Loveland. "Some people have said that repeating
other peoples'
experiments is like kissing your sister. But it's
a necessary
thing to do, not just for catching cases of fraud
but for
genuine mistakes."
And that, for the near term, may be the future
of the Lawrence
Berkeley team: confirming and extending other
labs'
blockbuster findings. Mr. Gregorich is trying
to gear up to
make a run for Element 114, which only the Dubna
lab, in
Russia, has seen thus far.
The same group has also reported hints of Elements
116 and,
recently, 118. If the Lawrence Berkeley team can
reproduce
those experiments, it may come as a form of vindication,
to
finally create the elusive element that sparked
so much
heartache.
