Abstract

Differential cross sections from ³He(π^±, π⁰) and ³He(π^±, π⁰p) measurements are presented. The π⁰ energy spectra from ³He(π^±, π⁰) and ³He(π⁺, π⁰p) are characteristic of quasi-free reactions. The proton angular distribution from ³He(π⁺, π⁰p) also show evidence of a quasi-free mechanism. Indications of multi-nucleon processes are presented in the ³He(π^-, π⁰p) data. At least two nucleons must be involved. Comparisons between coincidence and single-arm measurements from this work and previous measurements of charged pion scattering on ³He provide evidence of an enhanced multiple scattering contribution to the charge exchange channel.
