Abstract

摘要

The intrinsic level densities of superheavy nuclei and dinuclear systems are calculated using the single-particle spectra obtained with the modified two-center shell model. The role of the shell and pairing effects on the level density as well as their quenching with excitation energy are studied. The extracted level density parameter is expressed as a function of mass number, ground-state shell correction, and excitation energy. The results are compared with the phenomenological values of level density parameters
used to calculate the survival of excited heavy nuclei.
