摘要：
A measurement has been made of the differential cross section for the elastic scattering of positive and negative pions of energies 51, 60, 68, and 75 MeV scattered from helium. The experiment is discussed and a phase-shift analysis is presented. An optical-model analysis has been used to extract the pion electromagnetic radius, yielding 2.96±0.43 F. There remain uncertainties in this application of the model, which are discussed. © 1969 The American Physical Society.
