The nuclear level density parameter

الملخص

The nuclear level density parameter a in non Equi-Spacing Model (NON-ESM), Equi-Spacing Model (ESM) and the Backshifted Energy Dependent Fermi Gas model (BSEDFG) was determined for 106 nuclei; the results are tabulated and compared with the experimental works. It was found that there are no recognizable differences between our results and the experimental a-values. The calculated level density parameters have been used in computing the state density as a function of the excitation energies for 58 Fe and 246Cm nuclei. The results are in a good agreement with the experimental results from earlier published work.
