DYNAMICS OF THE SUPERHEAVY SYSTEM IN THE 86Kr + 208Pb REACTION

The main problem in planning the experiments aimed at the synthesis of super-heavy nuclides is the prediction of the formation of a compact compound super-heavy nucleus, which decays to the ground state by neutron- and γ-emission with a very strong fission competition. This, in turn, depends on the interplay of reaction channels and ultimately on the dynamics of the fusion-fission process. The reaction of 449 MeV 86Kr with 208Pb was used in an attempt to produce new super-heavy nuclei with Z = 118 [1]. Fragment mass and kinetic energy distributions for this reaction at near Bass barrier energies have been measured in Dubn
