Abstract: (APS)

Angular distributions for the elastic and inelastic scattering of 162 MeV π+ and π− by Si, Ni58, and Pb208 have been measured. The elastic scattering data are fitted with optical model calculations in configuration space. Momentum-space optical-model calculations qualitatively reproduce the elastic scattering data, but substantially better agreement can be obtained if suitable modifications to the model are made. Distorted-wave impulse approximation calculations of the inelastic scattering, using both configuration-space and momentum-space models, generally reproduce the experimental data. NUCLEAR REACTIONS Si28(π,π′), Ni58(π,π′), Pb208(π,π′), E=162 MeV, measured dσdΩ; optical potential and DWIA collective model analyses.
