Single neutron hole entropy in 105Cd and 111Cd

Abstract

The nuclear level density and entropy were calculated for105 Cd,106Cd,111 Cd and112Cd based on the Back Shifted Fermi Gas(BSFG) model and the Constant Temperature(CT) model. Then, the entropies were extracted in the microcanonical ensemble according to recent experimental data on nuclear level density measured by the Oslo group for these nuclei and are compared with their corresponding macroscopic calculations. Entropies of the neutron hole were estimated from the entropy difference between the odd-mass and even-even nuclei. The results reveal that the CT model describes better the extracted microcanonical results.
