Victor Ninov (Template:Langx; born June 27, 1959) is a Bulgarian physicist and former researcher who worked primarily in creating superheavy elements. He is known for the co-discoveries of elements 110, 111, and 112 (darmstadtium, roentgenium and copernicium, respectively).<ref name=":1"/>
Ninov also claimed the creation of elements 116 and 118 (now livermorium and oganesson);<ref name=":8" /><ref name="NYT20021015" /> however, an investigation conducted by the University of California, Berkeley concluded that he had falsified the evidence. The repercussions of the affair had an impact on the guidelines of conduct for several research institutions.
Early lifeEdit
Victor Ninov was born in Bulgaria in 1959.<ref>Template:Citation</ref> He grew up in the capital city of Sofia.<ref name=":3">Template:Cite news</ref> In the 1970s, when Ninov was a teenager, he and his family left for West Germany; they bounced around from house to house.<ref name=":0">Template:Cite magazine</ref> Shortly after the move, Victor's father went missing; he was found dead six months later in the Bulgarian foothills due to causes unknown.<ref name=":0" />
CareerEdit
Victor Ninov attended Technische Universität Darmstadt near Frankfurt, Germany.<ref name=":0"/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Here, he distinguished himself as a very capable physicist: he was particularly good at building scientific instruments and coding analysis programs for them.<ref name=":0" /><ref name=":1">Template:Cite journal</ref>
This landed him a job at the nearby German research center GSI (Helmholtzzentrum für Schwerionenforschung), where he worked on his doctorate and postdoctoral work of creating new elements.<ref name=":0"/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
For his expertise, he was given sole control of the computer analysis program.<ref name=":0" /> Here, he became a rising star by co-discovering darmstadtium (element 110), roentgenium (element 111), and copernicium (element 112) by smashing ion beams into heavy elements using GSI's UNILAC (a type of particle accelerator) and analyzing the debris.<ref name=":0" /><ref name=":1"/> Though an investigation later determined that these discoveries of element 110 and 112 included fabricated samples created by Ninov, additional evidence of the experiment was confirmed to be untampered with, rendering his co-discovery legitimate.<ref name=":1" /><ref name="Rg27202Ho01">Template:Cite journal</ref> These discoveries were made with the help of his addition of a gas separator to the particle accelerator to help filter out everything but the heavy elements they were looking for.
He worked at Stanford University for a time.<ref name=":3"/> He was hired at Lawrence Berkeley National Laboratory (LBNL) in 1996 as a world class expert for particle accelerator debris sensors, and analysis programs.<ref name=":0" />
Fraud investigationEdit
While working at Lawrence Berkeley National Laboratory (LBNL) Victor Ninov and his team pursued a hypothesis by Robert Smolańczuk, then a visiting fellow from Poland on a Fulbright scholarship,Template:Cn that element 118 could be formed at relatively low energies by smashing 86Kr and 208Pb isotopes together.<ref name=":2">Template:Cite news</ref><ref name=":0"/> This hypothesis was dubbed "Robert's magic recipe", and it was highly controversial at the time.Template:Cn Ninov initially doubted the hypothesis he was pursuing; he is quoted as saying, "We didn't know how many orders of magnitude he [Smolańczuk] was wrong".<ref name=":0" />
As in some earlier research projects, Ninov held sole control of the data analysis program (LBNL's was called GOOSY), and he was the only one on the team who knew how to use it.<ref name=":0" /> In 1999, Ninov and his team reported sightings of element 118, almost exactly as in Smolańczuk's hypothesis, and a decay chain that also produced element 116.<ref name=":0" /><ref name=":4">Template:Cite journal</ref><ref name=":1"/><ref name=":2" /> However, other laboratories were unable to reproduce the results.<ref name=":5">Template:Cite journal</ref>
Eager to prove their discovery, the team double-checked their instruments, and tried again.<ref name=":0"/> One more sighting was made by Ninov, but it was dismissed by a colleague, and a full formal investigation was held to find out what had happened.<ref name=":0" /> The original element 118 data was independently analysed; in the original binary data, there was no indication of the presence of element 118 or 116.<ref name=":0" /><ref name=":4"/><ref name=":1"/><ref name=":2"/><ref name=":5"/> The investigation dragged on for a year, until it was concluded that "Ninov ... intentionally misled his colleagues—and everyone else—by fabricating data".<ref name=":5" />
Ninov, who had been placed on leave for the investigation, was fired.<ref name=":0" /><ref name=":1" /> The rest of Ninov's team officially retracted their claims in 2002.<ref name=":4" /> There was also an investigation conducted into Ninov's previous unsupervised science at GSI; it was found that "two sightings were spuriously created" (one of element 110 and another of element 112).<ref name=":1" /><ref name="Rg27202Ho01"/> However these false sightings were found amongst a large amount of real data that still supported his co-discoveries of elements 110 and 112.<ref name=":1" /> The GSI investigation concluded that the discovery of those elements was legitimate.<ref name=":1" />
The superheavy elements 116 and 118 were eventually discovered and verified in the Joint Institute for Nuclear Research in Dubna, Russia from 2000–2002.<ref name=":5" /> These elements were named livermorium and oganesson respectively.<ref name=":8">Template:Cite journal</ref><ref name="NYT20021015">Template:Cite news</ref> In 2010, some of the nuclides that were originally claimed as decay products of element 118 were truly synthesized at LBNL; the 2010 observations did not match the claimed 1999 data.<ref name="281Cn"> Template:Cite news</ref> Ninov has continued to maintain that he was innocent.<ref name=":0"/>
Impact on the scientific communityEdit
The reports of the investigation came as quite a shock to other scientists, as Ninov had previously been regarded as a very respected physicist.<ref name=":0"/> He was so respected that Albert Ghiorso, a physicist who had part in the discovery of 12 elements and a close collaborator of Glenn Seaborg, once called Ninov "a younger version of himself". In the aftermath of the investigation, it was troubling to many that so many co-authors on LBNL's 1999 papers had contributed to a false statement while apparently unaware that it was false.<ref name=":6">Template:Cite journal</ref> The Ninov affair resulted in stricter guidelines being set for coauthors; these rules "clarify co-authors' roles and duties" and include "requiring all coauthors to vouch for their contribution to published work".<ref name=":6" /><ref name=":7">Template:Cite news</ref>
The American Physical Society has also called for increased ethical training and oversight at research institutions, and has sponsored several speakers in an effort to make the scientific community more comfortable and resilient to scientific fraud.<ref name=":7" /> Reports on the Ninov affair were released around the same time as the final report on the Schön affair, another major incident of data falsification in physics, and this amplified its impact.<ref name=":7"/>
Personal lifeEdit
Ninov is retired from physics.<ref name=":3"/> For a time, he worked as a professor of physics at the University of the Pacific, but it is said that he now holds an engineering job in California, where he currently lives.<ref name=":3" /> His wife, Caroline Cox, a former history professor at University of the Pacific, died in 2014 of cancer.<ref name=":3" /> They were married for 23 years.<ref name=":3" /> Ninov had helped her finish her book, Boy Soldiers of the American Revolution, and it was published posthumously.<ref name=":3" /> He is an avid sailor, and pilots a four-seat plane, an Aero Commander.<ref name=":3" />
