Chapter 13. Names mean more than numbers. —— p.175
At Dubna, the search for 273110 (September 10th to December 30th,
1994) actually started before our run. We first heard about it via a phone call
from Yuri Oganessian on New Year’s Day, 1995. Shortly thereafter, in
mid-January, Yuri Lazarev presented the results at our annual conference at
Hirschegg in Germany.
Chapter 14. Attack on the domain of superheavies: elements 114, 116 and 118. —— p.183
Experiments at the gas-filled separator GNS
...
At the beginning of the 1990s, Yuri Lazarev
and his colleagues had therefore started a programme to look at hot fusion
reaction using actinide targets; that was when cold fusion was predicted to
have no future. Possible actinide targets are the natural isotopes of thorium
and uranium (238Th, Z=90, 238U, Z=92) and lighter isotopes of uranium as
well as the synthetic isotopes of plutonium (242Pu and 244Pu, Z=94),
americium (243Am, Z=95), curium (248Cm, Z=96) and californium (249Cf, Z=98).
The first new result using the new GNS set-up was the identification
of the hitherto unknown isotopes 265Sg and 266Sg. The reaction was
22Ne + 248Cm → 270106*. The compound nucleus was hot (highly excited) and
five and four neutrons, respectively, had to be evaporated for the production
of the new isotopes. Only four atoms of 265Sg and six of 266Sg were observed.
Both nuclei decayed by α-emission; the measured α-energy was low but no
longer surprising as theory predicted low α-energies for nuclei close to
N=162. The experiment confirmed that.
...
Back to the Dubna GNS. The next step after synthesising element 106
by using hot fusion was to attempt to make element 108. Lazarev and
co-workers successfully did that, using 34S + 238U → 272108*. The new isotope
267108 was identified by parent/daughter correlation, a total of three decay
chains being measured. In November 1994 we confirmed the decay properties
of 267108 at SHIP, measuring this nucleus as daughter of the γ-decay of
271110.
In 1994, an unforeseen race started between Dubna and Darmstadt
over the new element 110. The contenders were hot fusion at Dubna,
starting in September, and cold fusion at Darmstadt, beginning in October (see
Chapter 12). ...
In Chapter 12, I have already described how the race was won in
Darmstadt, but Dubna was successful too. They had needed time for
the analysis of their data. On New Year’s Day, 1995, Oganessian
telephoned and informed Gottfried and me that one γ-decay chain had
been observed which was assigned to the nucleus 273110 having been
produced in the reaction 34S + 244Pu → 273110 + 5n; the production cross-section
was about 20 times less than in the cold fusion in Darmstadt. The Dubna
isotope had two more neutrons than our 271110 so we could not directly
compare the decay data. Later, from our data on the decay of 277112 which
produces 273110 as a daughter nucleus, we did not get 100% agreement but
the difference might be explained by the complicated decay pattern of this
nucleus.
Although our hunting of elements was competitive, the relations
between the people in Dubna and Darmstadt was that between colleagues
working in the same field. There were no secrets, results were exchanged
and our plans were discussed just as freely as ever. For example, the GSI
beam time schedule is accessible to everybody on our web site and I also
officially informed Lazarev of our finding as soon as the paper was
submitted. He answered by e-mail as follows:
Date: November 16, 1994
Dear Sigurd,
Thank you very much for the 110 news and please receive my sincere
congratulations. For me personally, the most impressive thing in
the whole of your work was your ability to produce and submit the paper
in so short a period of time, just five days. Let me joke that for
A. Ghiorso and co-workers it took about one thousand days. So, you
evidently have a gain of two orders of magnitude.
Speaking seriously, I wish you good luck with new 110 events, as well
as many forthcoming Short Notes to Zeitschrift fuer Physik A.
By now, we have collected a total beam dose of 1.2*10**19 for the
244Pu+34S reaction. We are starting the data analysis. The second
244Pu target wheel proved to be much more stable, so we continue
our bombardment at a good pace. I will inform you of the analyses
outcomes as soon as we have firm conclusions.
Best regards.
Yours,
Yuri Lazarev.
In January, 1995, I sent my own congratulations to Yuri (I could not do so
earlier because the computer in Dubna was shut down over the Orthodox
Christmas):
Dear Yuri,
Congratulations on your successful 110 experiment.
I got the news from Yuri Oganessian on our New Year’s day, Jan. 1st. I
think, for all of us – the low energy heavy element fusion people –
it was a great year.
There is certainly a good chance that you will find more in the data.
I wish you and your colleagues good luck, and a happy New Year 1995.
Best regards,
Yours,
Sigurd.
Sadly, and completely unexpectedly, Yuri Lazarev died early in 1996; the
group in Dubna had lost a leader and the heavy element community a
competent scientist and colleague.
For insiders it was clear that, after the 110 experiment, the people in
Dubna would like to go on to 112 and 114. An attractive projectile-target
combination would be 48Ca + 238U for element 112 and 48Ca + 244Pu for
element 114. This aim made the development of an intensive 48Ca beam
essential; it took until the autumn of 1998 to get it ready.

Table V.8
...
In Table V.8 are reported names that were previously contenders for elements with
atomic numbers 114, 116, and 118. These names were proposed more or less by their
presumed discoverers.
Following the recommendations of a JWP of experts drawn from IUPAC and IUPAP,
the IUPAC has officially approved the name flerovium, with symbol Fl, for the element of
atomic number 114 and the name livermorium, with symbol Lv, for the element of atomic
number 116.
In accordance with agreed-upon criteria, the Commission assigned priority for these
discoveries to the collaboration between the Joint Institute for Nuclear Research (Dubna,
Russia) and the Lawrence Livermore National Laboratory (Livermore, California). The
collaborating teams proposed the names flerovium and livermorium, which have now
been accepted and formally approved by IUPAC, thus contravening the IUPAC’s own
rules for not reusing the names and symbols of unsuccessful past candidates (see Table
V.8).

Впервые элемент был получен группой физиков под руководством Ю. Ц. Оганесяна в Объединённом институте ядерных исследований (Дубна, Россия) с участием учёных из Ливерморской национальной лаборатории (Ливермор, США); коллаборацией Дубна-Ливермор в декабре 1998 года.
...
1 июня 2011 года ИЮПАК официально признал открытие флеровия и приоритет в этом коллаборации учёных из ОИЯИ и Ливерморской национальной лаборатории[15][16]. Официальное утверждение названия произошло через год, 30 мая 2012 года[17]
...
Название флеровий было предложено учёными ОИЯИ и впервые официально озвучено вице-директором Объединённого института ядерных исследований Михаилом Иткисом[24], который также был одним из соавторов открытия. Однако американские партнёры ОИЯИ из Ливерморской национальной лаборатории предложили назвать 114-й или 116-й элемент в честь Леонардо да Винчи, Галилео Галилея или в честь Ливерморской национальной лаборатории[25]. Среди других предложений были атлантисий (англ. Atlantisium, An, отсылка через Атлантиду к острову стабильности), лазаревий (англ. Lazarevium, Lz, в честь Юрия Лазарева) и оганесий (англ. Oganessium, Og, в честь Юрия Оганесяна)[26]. После согласовательных процедур между российскими и американскими учёными 1 декабря 2011 года в комиссию по номенклатуре химических соединений ИЮПАК было направлено предложение назвать 114-й элемент флеровием[21][22]. Название утверждено 30 мая 2012 года[17].
