Summary:An analysis of [pi] super(+ or -)-nucleus elastic and inelastic scattering has been performed using local semi-microscopic optical potentials constructed in the framework of the single folding approach. The folding calculations are carried out based upon the alpha -cluster structure of the target nuclei with two different phenomenological forms of the pion-alpha effective interaction. The derived potentials have been employed to extract the angular distributions of elastic and inelastic scattering cross sections through a broad energy range, 100-766 MeV, where 39 sets of data have been successfully described. The corresponding reaction and total cross sections have also been extracted.
