The single particle level density calculations for 232 th 90 using equidistant space model (ESM)‎ and NON-ESM in fermi gas model

Abstract EN

The single-particle level densities for Th 232 90, 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 Th 232 90.

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.
