Abstract
The transition operator for threshold charged-pion photoproduction and radiative pion capture is utilized in its nonrelativistic limit to calculate the absolute rate for the reaction from a atomic orbital in the impulse approximation. Sensitivity to assumptions concerning the initial state of the system and the short-range character of the wave function in the final state is discussed, as is the relevance of the absolute rate to the determination of the scattering length from this reaction.
