Validation of the microscopic level density models for nuclei near the Z = 28 shell closure

Le résumé fourni par la source

A comprehensive test of level density models for explaining the decay of excited compound nuclei $^{54}\mathrm{Mn}$, $^{56}\mathrm{Fe}$, $^{58}\mathrm{Co}$, $^{60}\mathrm{Ni}$, $^{61}\mathrm{Ni}$, and $^{63}\mathrm{Cu}$ in the energy range of 28--36 MeV was performed. The compound nuclei of interest in the desired ranges were populated using $^{6}\mathrm{Li}$ based transfer reactions. The proton decay spectrum for each excitation energy bin was measured. The measured proton spectrum was reproduced using statistical model calculations with different level density models. A variance minimized approach was employed for analyzing the prediction capability of different level density models. This approach was converged to the Gogny Hartree-Fock-Bogoliubov (HFB) microscopic level density model, which is considered the most accurate model for the desired nuclei.
