Nuclear excitations at constant temperature
Physical Review C—Nuclear Physics, 2009•APS
Neutron and proton evaporation spectra from the Li 6+ Mn 55 and d+ Co 59 reactions have
been analyzed with the Hauser-Feshbach approach using different input models for nuclear
level densities of Ni 60 and Co 60 nuclei. It has been found that models with a Fermi-gas like
temperature dependence fail to reproduce particle spectra from both reactions
simultaneously. We obtained the surprising result that the only way to describe our data is to
assume the independence of the nuclear temperature on the excitation energy up to about …

It has been found that models with a Fermi-gas like temperature dependence fail to reproduce particle spectra from both reactions simultaneously. We obtained the surprising result that the only way to describe our data is to assume the independence of the nuclear temperature on the excitation energy up to about the 20 MeV energy range.
