SYSTEMATIC STUDY OF SURVIVAL PROBABILITY OF EXCITED SUPERHEAVY NUCLEI
In this contribution we present some results of a study of the stability of excited superheavy nuclei (SHN) with 100 < Z < 134 against neutron emission and fission. We give a systematic investigation of the survival probability against fission in the lnchannel of these SHN. The neutron separation energies and shell correction energies are consistently taken from the finite range droplet model which predicts an island of stability of superheavy nuclei around Z = 115 and N = 179. It is found that this island of stability persists for excited superheavy nuclei in the sense that the calculated survival probabilities in the ln-channel of excited superheavy nuclei at the optimal excitation energy are maximized around Z = 115 and N = 179. This indicates that the survival probability in the ln-channel is mainly determined by the nuclear shell effects.
