摘要

Neutron evaporation spectra have been measured from He-4+ Pb-208 and He-4+ Bi-209 reactions by using He-4-ion beams of several bombarding energies. Excitation-energy dependence of the level density parameter has been studied for the two systems in the excitation energy range of similar to 18-50 MeV. For both the reactions an overall reduction of the asymptotic level density parameter with increasing excitation energy (temperature) is observed. The trend of the data was compared with the Thomas-Fermi model predictions and found to be in reasonable agreement. The value of the shell damping parameter has been extracted from the lowest-energy data in the case of Po-210,Po-211 and At-211,At-212 nuclei close to the Z = 82 and N = 126 shell closure, and it was found to be consistent with the recent measurement in the vicinity of doubly magic Pb-208 nucleus.
