Berkeley -- Officials at Lawrence Berkeley National Laboratory have
concluded that a sensational but false claim about the discovery of two
new elements was based on fraudulent research, the second case of
scientific misconduct revealed by the federal energy lab in three years.
Originally hailed as a "stunning discovery" into the structure of
the atomic nucleus, the finding was retracted by Lawrence Berkeley lab
last year after independent scientists were unable to duplicate the
results. Lab officials then undertook an investigation.
Lab Director Charles V. Shank acknowledged in a speech to employees
last month that the false claim was "a result of fabricated research
data and scientific misconduct by one individual," according to a
summary of his remarks in a lab newsletter.
"There is nothing more important for a laboratory than scientific
integrity, " Shank reportedly told employees. "Only with such integrity
will the public, which funds our work, have confidence in us." In this
case, he said, "the most elementary checks and data archiving were not
done."
Although lab spokesman Ron Kolb declined to identify the
individual, citing personnel rules, The Chronicle has learned that lab
investigators identified Victor Ninov, a respected expert on the physics
of heavy elements, as the scientist behind the fraudulent data.
SCIENTIST FILED GRIEVANCE
The lab suspended Ninov in November and terminated his employment
after the misconduct finding. Ninov, who has filed a grievance against
the lab, could not be reached for comment Friday.
In 1999, the federal Office of Research Integrity found that
Lawrence Berkeley lab scientist Robert P. Liburdy had committed
"scientific misconduct" by "intentionally falsifying and fabricating"
his data to support assertions of cellular effects from electric and
magnetic fields. Liburdy resigned from the lab after the lab yanked his
financing.
The Ninov case is more dramatic because it supposedly involved a
discovery of great importance to our understanding of the periodic table
of elements, a copy of which hangs on the wall of every high school
chemistry teacher's classroom.
The world of physics was thrilled in May 1998, when laboratory
officials announced their researchers had discovered the heaviest known
element, the "superheavy" element dubbed 118, and its decay product 116.
(The numbers refer to the elements' location on the periodic table of
elements.)
They managed to generate "118," they claimed, by using the lab's
88-inch cyclotron, a particle accelerator, to fire a beam of krypton
atoms onto lead.
The research team was led by Ninov, a native of Bulgaria who had
come to the lab several years earlier. The team reported its findings in
the journal Physical Review Letters in an article titled, "Observation
of superheavy nuclei produced in the reaction of Krypton-86 with
Lead-208."
Then-Energy Secretary Bill Richardson called it "a stunning
discovery which opens the door to further insights into the structure of
the atomic nucleus."
Ninov was the first of 15 authors listed for the Physical Review
article. The second author, lab scientist Kenneth Gregorich, declined to
comment Friday.
None of the other authors is suspected of participating in the
fraud.
COLLEAGUES RETRACTED CLAIM
In follow-up experiments, outside labs were unable to replicate the
earlier results. Some members of the Berkeley team submitted a follow-up
report to Physical Review Letters that retracted the original claim.
At that time, Gregorich told Physics Today that he and his
colleagues were trying to figure out what had gone wrong. "There's been
quite a bit of experimental and theoretical work based on our 1999 data,
so that we felt we needed to get the word (of subsequent failure) out,"
he said.
On Friday, lab spokesman Kolb stressed that some personnel were
suspicious of the reported findings early on.
"The one thing we want to emphasize more than anything is that we
had ferreted this out on our own," Kolb said. "Nobody externally came to
us and told us, 'This (scientific finding) looks crazy, you ought to
check it out.'"
In his speech disclosing the fraud to employees, lab director Shank
ended with a sobering message on scientific integrity.
"Emphasizing that the lab will vigorously pursue all issues
involving scientific integrity, Shank said many lessons have been
learned from the Element 118 experience, including one 'that all
co-authors have a responsibility before a paper is published to verify
the data,' " the lab's newsletter said.
'COMMITMENT TO INTEGRITY'
But Shank told employees: "I am proud of the intensity and
professionalism of the (internal) review to get to the bottom of this,
and of the commitment of the laboratory to the highest level of
scientific integrity."
Asked why the lab did not announce the fraud publicly, Kolb
explained that lab Director Shank felt "he had to balance the importance
of getting a very strong statement to the lab community about the
importance of integrity and, at the same time, not to jeopardize the
personnel (grievance) actions that are continuing."
Reported cases of scientific fraud are rare but hardly unknown. One
of the most tragic occurred in the 1920s, when a respected Austrian
scientist was suspected of injecting ink into laboratory frogs in order
to prove one of his pet theories. After being accused of fraud, he
committed suicide.
In recent decades, historians of science have debated whether some
of the most famous scientists in history faked or "fudged" their
results, including the great ancient astronomer Ptolemy and the famed
20th century British psychologist Cyril Burt.
The Berkeley laboratory, named in honor of Nobel Prize-winning
physicist Ernest Lawrence, was founded in 1931 under the name Radiation
Laboratory. It has 4,000 employees and does no military or classified
research, Kolb said.
