The total cross section for the reaction /sup 12/C(..gamma..,..pi../sup -/)/sup 12/N has been determined by observation of the residual /sup 12/N radioactivity. The cross section was extracted from the bremsstrahlung excitation function which was measured in the region between 3.6 and 12.6 MeV above the threshold, with one point 33.5 MeV above the threshold. The variation of the measured cross section with energy is far more rapid than is predicted by calculations using the epsilon-arrow-rightxsigma-arrow-right interaction. Even when the full interaction Hamiltonian is used, the experimental cross section rises somewhat more rapidly than predicted. (AIP)
