Microscopic optical potentials for nucleon-nucleus scattering obtained from folding the calculated G-matrices with RMF densities of the target have been used to analyze the 65 MeV proton and neutron-nucleus scattering data over a wide mass region. The soft-core Argonne AV14, AV18 and the old hard-core Hamada-Johnston inter-nucleon potentials have been used to calculate the G-matrices in the Brueckner-Hartree-Fock approach. The calculated potentials have been used to analyze the differential elastic cross-section, analyzing power and spin-rotation function for neutron and proton scattering at 65 MeV from C-12 to Pb-208. Our results are in satisfactory agreement with the experimental data. Comparison of our results with phenomenological optical model analyses is also presented. Mass number dependence of the mean square radii of real central optical potential < r(2)>(pot). for the microscopic potentials used here is found to be in close agreement with each other as well as with empirical results. We also present our results for proton reaction cross-section from C-12 to Zr-90 in the energy region 20-200 MeV.
