A statistical optical potential has been used to analyze andevaluate the neutron interaction with heavy nuclei 197Au at theneutron energy range (1-20 MeV). Empirical formulae of the opticalpotentials parameters are predicted by using ABAREX Code withminimize accuracy compared with experimental bench work data.The total elastic, absorption, shape elastic and total compound crosssections are calculated for different target nuclei and differentincident neutron energies to predict the appropriate opticalparameters that suit the present interaction. Also the dispersionrelation linking between real and imaginary potential is analyzedwith more accuracy. The results indicate the behavior of thedispersion contribution in imaginary potential has a parabolic changeabout the Fermi surface energy while in the real potential it fall withincreasing the neutron energy. Good agreements have been achievedwith the available experimental data
