Both Flerovium and Livermorium were detected in Russian labs over ten years ago (1998 and 2000), but the half-lives of the particles were so short that the scientists were unable to verify their discoveries. The discoveries were confirmed in 2004 through a collaborative effort scientists from the Joint Institute for Nuclear Research (JINR) in Dubna, Rusia, and the Lawrence Livermore National Laboratory (LLNL) in Livermore, California, USA, led by Rusian physicist Yuri Tsolakovich Oganessian (1933-) and American chemist Kenton J. (Ken) Moody. The Dubna-Livermore collaboration be credited with the discovery of the new element with Z = 116. Livermorium, previously known as ununhexium, received its name from the Lawrence Livermore National Laboratory. It is a synthetic radioactive element that do not occour naturally in earth. Livermorium was produced by bombarding curium-245 with calcium-48.
