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.
