Abstract

The three body approximation of the pion-nucleus optical model is used to calculate effective strengths to be used in conventional calculations. The resulting wave functions are used to calculate pion elastic scattering and single charge exchange. It is found that observed energy shifts in elastic scattering can be understood. Considerable change in the magnitude and shape (as a function of energy) of the charge exchange cross section is a direct result of these corrections.
