Abstract from JINR News, 4 March 1999

At the Flerov Laboratory of Nuclear Reactions, a group of scientists headed by Professor Yu.Ts.Oganessian in collaboration with the colleagues from the Lawrence Livermore National Laboratory (USA) synthesized a new long-lived (30s) superheavy element of the Periodic Table with atomic number 114 and mass 289.

This discovery sums up many-year efforts of experimental physicists from Russia, USA, and Germany to search for a stability island of superheavy elements predicted and discussed by theoretical physicists in various countries for the past 35 years.

The discovery of the stability island of superheavy elements has become possible owing to the unique parameters of the experimental facility, which records extremely rare events of formation and decay of nuclei, and the record intensities of the accelerated ⁴⁸Ca ion beams.

The discovery of flerovium, as ²⁸⁷Fl and ²⁸⁶Fl, was confirmed in January 2009 at Berkeley. This was followed by confirmation of ²⁸⁸Fl and ²⁸⁹Fl in July 2009 at the GSI.

The element was named Flerovium on 31 May 2012. Formerly it was known under the systematic IUPAC name Ununquadium (system explained here).

According to IUPAC recommendations, the discoverer(s) of a new element has the right to suggest a name. The discovery of ununquadium was recognized by JWG of IUPAC on 1 June 2011, along with that of ununhexium. According to the vice-director of JINR, the Dubna team chose to name element 114 flerovium (symbol Fl), after the founder of the Russian institute, Flerov Laboratory of Nuclear Reactions, the Soviet physicist Георгий Николаевич Флёров (Georgy Flyorov, also spelled Flerov). However, IUPAC officially named flerovium after the Лаборатория ядерных реакций им. Г.Н. Флерова (Flerov Laboratory of Nuclear Reactions), not after Flerov himself. Flerov is known for writing to Stalin in April 1942 and pointing out the conspicuous silence in scientific journals within the field of nuclear fission in the United States, Great Britain, and Germany. Flyorov deduced that this research must have become classified information in those countries. Flyorov's work and urgings led to the eventual development of the USSR's own atomic bomb project
