MOSCOW, Oct. 24 — RIA Novosti. The ceremony naming the 114 th and 116 th elements of the periodic table, for the first time synthesized by physicists from Dubna near Moscow, will be held today in Moscow’s Central House of Scientists RAS.
- Geo? Rgy Nikola? Evich Flyorov (February 17 (March 2), 1913, Rostov-on-Don — November 19, 1990, Moscow) — Soviet nuclear physicist, founder of the Joint Institute for Nuclear Research in Dubna, USSR Academy of Sciences (1968) and the Academy Yuri Hovhannisyan
Element under the number 114 was obtained in 2000 by bombardment in the cyclotron target of plutonium-242 nuclei of calcium-48, and the 116th element — in 2004, in the reaction of calcium-48 and curium-245. These experiments were conducted by a team of scientists Laboratory of Nuclear Reactions Flerov Joint Institute for Nuclear Research (JINR), under the guidance of Academician Yuri Hovhannisyan with the participation of American colleagues from the Lawrence Livermore National Laboratory.
In May 2012, the International Union of Pure and Applied Chemistry (IUPAC) adopted a proposal
On Wednesday, the Central House of Scientists of the RAS will be an official ceremony "naming". At the ceremony will be attended by members of experiments on the synthesis of new elements, also invited the leaders of Russian Academy of Sciences, representatives of the Ministry of Education of the Russian Federation, the Moscow authorities and the Moscow region, are expected to visit the City Hall of Livermore.
In the "christening" will also be attended by President of IUPAC Katsuyuki Tatsumi (Kazuyuki Tatsumi) and members of the executive committee of the IUPAC.
Previous ceremony "baptism" of the new element was held in July 2010 in the Helmholtz Center Heavy Ion Research (GSI), located in Darmstadt (Germany). Then the 112-th element of the periodic table
Between the "christening" and the synthesis of new elements of the past 14 years. Group of German physicists led Zigurda Hoffmann (Sigurd Hofmann) won the 112th element in 1996.
Now the new joint working group established by the Bureau of IUPAC, began work to establish priority in the preparation of other, unnamed until the superheavy elements — the 113th, 115th, 117th and 118th.
Officially recognized pioneers will have the right to propose names for them. In June of this year, scientists from Dubna have applied for recognition in the IUPAC 113th, 115th, 117th and 118th elements — all of which were first synthesized at JINR.
