Extracting nuclear level density of 166Er using microscopic theory of interacting fermions Original Research Article

Determination of accurate nuclear level densities is of crucial importance for a variety of pure and applied nuclear physics. The density of accessible levels is calculated for 166Er nucleus using the microscopic theory of interacting fermions and is compared with experimental data. It is shown that the data can be reproduced by a level density formalism developed for nuclei with static deformation. Our results are in a good agreement with the experimental data obtained by the Oslo group.
