Recent experimental results on level densities for compound reaction calculations

Abstract

Proton evaporation spectra from 6,7 Li induced reactions on 54,56,58 Fe nuclei have been measured and analyzed with Hauser-Feshbach compound reaction calculations with a Gilbert and Cameron input level density model. Level densities of residual 59 64 Ni nuclei have been extracted from proton spectra. Both level density and level density pa- rameter a have been compared against the respective values obtained from neutron res- onance spacing data. The discrepancy has been found in systematics behavior of level densities against the mass number of Ni isotopes.
