The nucleon-nucleus optical potential has been obtained from calculations of the mass operator of the one-particle Green function with the effective nucleon-nucleon density-dependent Skyrme interaction by perturbation theory up to the second order. By means of fitting angular distributions of nucleon-nucleus scattering with simultaneous control of calculated characteristics of the nuclear matter, binding energy and rms radius of the target nucleus new variants of Skyrme-force parameters have been found. Analyses of differential cross sections and analyzing powers of elastic neutron scattering by nuclei in a wide range of mass numbers have been carried out. It has been shown that using the found Skyrme-force parameters enables us to describe satisfactorily both the main nuclear structure characteristics and the experimental data on elastic neutron-nucleus scattering simultaneously.
