描述 • 用途/功能

In 1987 Oganessian, et al., at Dubna, claimed discovery of this element. Their experiments indicated the spontaneous fissioning nuclide Element 110-272 with a half-life of 10 ms. More recently a group led by Armbruster at G.S.I. in Darmstadt, Germany, reported evidence of Element 110-269, which was produced by bombarding lead for many days with more than 10^18 nickel atoms. A detector searched each collision for Element 110’s distinct decay sequence. On November 9, 1994, evidence of 110 was detected. Berkeley scientists, in 1991, performed similar experiments and reported evidence of 110, but this was not confirmed. Workers at Dubna have experiments underway to produce Element 110-273 by bombarding plutonium with sulfur atoms. Other experiments at G.S.I. are now searching for heavier isotopes. Several years ago the IUPAC suggested the use of the temporary name ununnilium for Element 110 when it was found. 1
