Popis:	Phenomenological models that calculate the nuclear level densities (NLDs) based on the famous Fermi gas model are the most widely used models for practical applications, especially in nuclear reaction and evaporation codes. However, results of the most recent microscopic methods for calculation of NLDs indicate that the high-energy behavior of NLDs beyond approximately 30–50 MeV cannot be well described by these phenomenological models. In this research, using the results of microscopic spectral distribution method at high energies, a new relation for energy dependent NLD parameter is presented and using this new relation, these high-energy microscopic results and low energy experimental data can be well reproduced by Fermi gas phenomenological models.
