Low-energy-pion elastic scattering from light nuclei

· Physical Review. C, Nuclear Physics
Simple $pi$-nucleus optical potentials constructed from $pi$-N phase shifts yield poor fits to elastic scattering from He and C below 75 MeV. Forcing a fit gives potentials which are pion producing or in violation of unitarity. The forward position (approx.65degree) and breadth of the minimum are shown to be partially responsible. These features are also shown to require a much stronger s-wave interaction with nuclei than that derived from $pi$-N scattering. (AIP)
