Abstract

Elastic cross sections have been measured for the scattering of π+ and π from O16 at 114 MeV in the angular range of 115° to 175° (c.m.). Large cross sections and large π+/π differences have been observed beyond 140° (c.m.). First-order optical model calculations fail to reproduce the large-angle data. Second-order effects generally improve the fits, but the details of the present data together with the results of earlier measurements at smaller angles have not been satisfactorily explained.
