Consistent Interpretation of the Secondary-Reaction Experiments in W Targets and Prospects for Production of Superheavy Elements in Ordinary Heavy-Ion Reactions

The chemical separation of Eka-Hg from CERN W targets in view of recent relativistic calculations

“…Based on experimental data and on extrapolation of the periodic table this low temperature eliminates any element with 90 ≤ Z ≤ 111. The masses of the fissioning species were measured and interpreted as due to the atom and various molecules of the ∼272 112 nucleus, where the molecules are known to be common molecules formed with Hg itself [3].…”

“…Based on the extrapolation of the periodic table the fission activity was interpreted as due to production, via secondary reactions, of the superheavy element with Z = 112. The masses of the fissioning species were measured and heavy masses like 272, 308 and 317-318 were found and consistently interpreted as due to element 112 with 160-161 neutrons and various molecules of it [3]. From the measured mass of the produced superheavy nucleus cold fusion reactions like 88 [3].…”

From the measured mass of the produced superheavy nucleus cold fusion reactions like 88 [3]. The ordinary heavy ion reaction 88 Sr + 184 W has been studied and characteristic X-rays of element 112 in coincidence with low energy particles (interpreted as protons) and a very high-energy α particle (E α = 12.16 MeV) in coincidence with a fission fragment were found [4].…”
