Regularities of formation and survival probability of compound nuclei in the region of Z >= 82: Study of complete-fusion reactions with heavy ions using the kinematic separator VASSILISSA

摘要

In the last 15 years, the electrostatic separator VASSILISSA has been used for studying evaporation residues produced in the complete-fusion reactions induced by heavy ions. The decay properties and the cross sections for the formation of isotopes of elements with atomic numbers Z >= 82 have been studied experimentally. The obtained results, together with data from other recoil separators, were used for studying the formation regularities and the survival probabilities of excited compound nuclei.
