Level Densities of Nuclei with Z = 112–120

Level densities of superheavy nuclei with Z = 112–120 in the ground state and at the saddle point are calculated using single-particle spectra obtained in a macroscopic and microscopic model based on the Woods–Saxon single-particle potential. Level density parameters are calculated by fitting the re...

Description
Summary:	Level densities of superheavy nuclei with Z = 112–120 in the ground state and at the saddle point are calculated using single-particle spectra obtained in a macroscopic and microscopic model based on the Woods–Saxon single-particle potential. Level density parameters are calculated by fitting the results with the expression of a Fermi gas. The role of shell correction and pairing effects in the behavior of the level density parameter in the ground state and at the saddle point is studied. The results from calculations are compared to phenomenological expressions. The ratio of the level density parameter at the saddle point to its values in the ground state is presented.
