TLDR
At low excitation energies a constant nuclear temperature representation of nuclear-level densities was used, and at high excitation energy the regular Fermi gas formula was adopted as mentioned in this paper.Abstract:
At low excitation energies a "constant nuclear temperature" representation of nuclear-level densities is used, and at high excitation energies the regular Fermi gas formula is adopted. A method is ...read more

Local and global nucleon optical models from 1 keV to 200 MeV
Arjan J. Koning,J.P. Delaroche +1 more
TL;DR: In this article, the authors presented new phenomenological optical model potentials for neutrons and protons with incident energies from 1 keV up to 200 MeV, for (near-)spherical nuclides in the mass range 24⩽ A ⩽209 They are based on a smooth, unique functional form for the energy dependence of the potential depths, and on physically constrained geometry parameters.

An Attempt to Calculate the Number of Energy Levels of a Heavy Nucleus
TL;DR: In this paper, the authors proposed a statistical method to calculate the number of levels of the complete nucleus in a given energy interval irrespective of the angular momentum of the nuclei, which will, for most of the levels, be very large.
