The dispersion in spherical statistical optical potential (SOM)‎ from the interaction of fast neutrons with197au nuclei

الملخص EN

A statistical optical potential has been used to analyze and evaluate the neutron interaction with heavy nuclei 197Au at the neutron energy range (1-20 MeV).

Empirical formulae of the optical potentials parameters are predicted by using ABAREX Code with minimize accuracy compared with experimental bench work data.

The total elastic, absorption, shape elastic and total compound cross-sections are calculated for different target nuclei and different incident neutron energies to predict the appropriate optical parameters that suit the present interaction.

Also the dispersion relation linking between real and imaginary potential is analyzed with more accuracy.

The results indicate the behavior of the dispersion contribution in imaginary potential has a parabolic change about the Fermi surface energy while in the real potential it fall with increasing the neutron energy.

Good agreements have been achieved with the available experimental data
