Elastic cross sections have been measured for the scattering of ..pi../sup +/ and ..pi../sup -/ from /sup 16/O at 114 MeV in the angular range of 115/sup 0/ to 175/sup 0/ (c.m.). Large cross sections and large ..pi../sup +//..pi../sup -/ differences have been observed beyond 140/sup 0/ (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.
