p+-nucleus scattering cross section are calculated by solving a Schrödinger
equation reduced from the Klein-Gordon equation. Local potentials are assumed, and
phenomenological potential parameters are searched energy dependently for p+ scattering from 12C, 40Ca, and 208Pb
to reproduce not only differential elastic cross sections but also inelastic and total and
reaction cross sections at 800 MeV/c pion laboratory momentum. The collective model is
used to calculate the angular distributions of differential inelastic cross sections for
pions leading to the lowest 2+ and 3-
states of 12C. The deformation parameters and lengths are extracted and
compared to the corresponding ones from other works. Local potentials well describe the
scattering of pions from nuclei.
