Pion scattering from C and Ca at 800 MeV/c

Results from π^± elastic and inelastic scattering from ¹²C and ⁴⁰Ca are reported. The data were all taken at an incident momentum of 800 MeV/c over an angular range from 4^∘{} to 38^∘{}. The elastic data are compared to first-order optical model calculations in momentum space; qualitative agreement is obtained. The inelastic data (from ¹²C only) are compared to distorted-wave Born approximation calculations, and reasonable agreement is found if realistic inelastic transition densities are used.
