Study of collective rotational enhancement factors for nuclear level densities using the microscopic theory of interacting fermions

Abstract

Determination of accurate nuclear level densities is of crucial importance for a variety of nuclear physics aspects and its related technologies. Therefore, there have been many theoretical and experimental efforts to determine nuclear level densities for variety of nuclei. In this research, the effects of changing structure and collective excitations on some deformed nuclei with axial symmetry were studied using microscopic generalized superfluid model (MGSFM) and experimental data. It was shown that the experimental data can be reproduced by a level density formalism developed for nuclei with static deformation.
