Angular distributions for the elastic and inelastic scattering of 162 MeV ..pi../sup +/ and ..pi../sup -/ by Si, /sup 58/Ni, and /sup 208/Pb 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.
