Neutron total and differential elastic scattering cross sections have been calculated for the elements Na, Al, Si, V, Mn, Fe, Co, Ni, Cu, Y, Nb and Pb in the energy range of 1.5 to 8.5 MeV and in steps of 0.5 MeV. The calculations have been done on the basis of the nuclear optical model using a set of generalized optical model parameters which are independent of the incident neutron energy but are a function of mass number. The compound elastic contribution to the elastic scattering cross section has been calculated using Hauser-Feshbach formalism. The calculated neutron classic scattering angular distributions have been compared with those measured by different experimenters to check the validity of the generalized optical model parameters for estimation of the elastic scnttering cross sections for applied purposes. Comparisons have also been made between the calculated total and total elastic cross sections of the present work and the corresponding experimental data found in the literature. (auth)
