Abstract

The temperature dependence of the recently synthesized superheavy nucleus Z = 117 is extensively studied through the statistical model for a wide range of isotopes. The model code is developed and executed for calculating the excitation energy, single neutron separation energy, level density, and entropy for the hot system. The possible sub-magic and magic numbers predicted are 178, 184, and 196. It is found that the pairing correlation collapses at T = 0.8 MeV and shell effect vanishes at T = 2.5 MeV. The limiting temperature is determined from the behavior of the level density parameter as a function of temperature.
