Measurements of the angular distributions of the single charge exchange reactions to isobaric analog states for /sup 13/C(..pi../sup +/,..pi../sup 0/)/sup 13/N and /sup 15/N(..pi../sup +/,..pi../sup 0/)/sup 15/O at 165 MeV are described. The two angular distributions are very similar. The shapes are reproduced by semiphenomenological isobar-doorway calculations and by second-order coupled channels calculations. The calculated magnitudes are low by about a factor of 2. Phenomenological calculations that agree with small-angle excitation functions do not reproduce the angular distributions. The measurements are consistent with older angle-integrated cross sections for /sup 13/C.
