The Single Particle Level Density Calculations for Using Equidistant Space Model (ESM) and NON-ESM in Fermi Gas Model

Abstract

The single-particle level densities for , at certain exciton number, are calculated in terms of Equidistant Space Model, ESM, and NON-ESM, of Fermi Gas Model. It is found that the single particle level density, g, has no longer a constant value and becomes an energy dependent on the contrary with NON-ESM. The finite depth of the nuclear well and pairing corrections are examined with behavior of the single level density for both models. The particle-hole state density has been calculated, by means of the energy dependence of excited particles and hole level densities, for one and two fermions systems and different exciton number in . The present results are compared between two models with and without the inclusion of the finite well depth correction. NON-ESM system has a major effect in the present calculations at high excitation energies.
