Abstract
The scattering of pions by light nuclei is calculated using an approximate, high-energy, small-angle multiple-scattering expansion which neglects off-the-energy-shell scattering. The approximations needed to obtain this expansion from an exact multiple-scattering theory are examined. It is found that the unknown contribution of the off-the-energy-shell scattering makes any calculation of pion-nucleus scattering unreliable for large angles. Using pion-nucleon phase shifts and electron-scattering data, results are obtained for the scattering of pions of about 80 MeV by lithium, carbon, and oxygen.Keywords
