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 ..pi../sup -/d ..-->.. ..gamma..nn reaction from a 1s atomic orbital in the impulse approximation. Sensitivity to assumptions concerning the initial state of the ..pi../sup -/d system and the short-range character of the n-n wave function in the final state is discussed, as is the relevance of the absolute rate to the determination of the n-n scattering length from this reaction.
