Charged pion photoproduction cross sections from /sup 9/Be, /sup 10/B, and /sup 13/C have been calculated for photon energies of 180 to 500 MeV. The shell model wave functions of Cohen-Kurath have been used for the nuclei and the elementary amplitude of CGLN has been used in the context of plane wave impulse approximation. The final state interactions for positive pion photoproduction from /sup 13/C at 193 MeV photo energy have been included in the calculation by employing Kisslinger, Modified Kisslinger, and Local Laplacian optical potential models as well as the Coulomb distortions. These same optical potential models have been used to calculate elastic pion scattering from /sup 13/C for 50 MeV pions. The calculations using plane wave pions in general tend to disagree with the experimental points by more than a factor of three. In the case of positive pion photoproduction from /sup 13/C using distorted pion waves it is found that from the three optical potential models used the Local Laplacian, which results in the best agreement with the experiment when used in the pion scattering process, tends to generate results in good agreement with the experimental data.
