Elastic cross sections have been measured for the scattering of π+ and π- from 16O at 114 MeV in the angular range of 115°to 175°(c.m.). Large cross sections and large +/- 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.
