Livermorium: historical information

Livermorium was discovered by Yu.Ts. Oganessian, V.K. Utyonkov, Yu.V. Lobanov, F.Sh. Abdullin, A.N. Polyakov, I.V. Shirokovsky, Yu.S. Tsyganov, G.G. Gulbekian, S.L. Bogomolov, B.N. Gikal, A.N. Mezentsev, S. Iliev, V.G. Subbotin, A.M. Sukhov, O.V. Ivanov, G.V. Buklanov, K.Subotic, M.G. Itkis, K.J. Moody, J.F. Wild, N.J. Stoyer, M.A. Stoyer, R.W. Lougheed, C.A. Laue, Ye.A. Karelin, and A.N. Tatarinov at 2000 in Dubna, Russia. Origin of name: temporary systematic IUPAC nomenclature.

Results published on the 6th December 2000 concerning recent experiments at Dubna in Russia (involving workers from The Joint Institute for Nuclear Research, Dubna, Russian Federation; The Lawrence Livermore National Laboratory, California, USA; The Research Institute of Atomic Reactors, Dimitrovgrad, Russian Federation; and The State Enterprise Electrohimpribor, Lesnoy, Russian Federation) describe the decay of the isotope 292Uuh (produced in the reaction of 248Cm with 48Ca) to 292Uuq.

24896Cm + 4820Ca → 292116Lv + 4 n

This decayed 47 milliseconds later as follows to a previously identified isotope of elements 114, flerovium, Fl.

292116Lv → 288114Fl + 42He
