An analysis of π±-nucleus elastic and inelastic scattering has been performed using local semimicroscopic
optical potentials constructed in the framework of the single folding approach. The
folding calculations are carried out based upon the α-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.
