Abstract
The influence of nuclear structure upon calculated angular distributions and cross sections of pion scattering off light nuclei is studied within the framework of Glauber theory. Both spin-flip and non-flip processes are included. Results obtained using simple shell-model configurations as well as more realistic shell-model wave functions which may involve particle-hole components are compared. The effects of using realistic single-particle wave functions generated from Woods-Saxon potentials, effects of antisymmetry, renormalisation of the properties of the Δ( 3 2 , 3 2 ) isobar in the nucleus and renormalisation of the effective charge are investigated. Results are given for elastic scattering on 12C, 16O and 24Mg and inelastic scattering on 7Li, 12C, 15N, 20Ne and 24Mg. It is shown that pion-inelastic scattering to excited levels in 15N can give important details of the nature of the particle-hole admixtures. Large effects were found for the calculated angular distributions in 20Ne when the model space was enlarged to include the d 3 2 orbit.
