We report new measurements of ..pi../sup plus-or-minus/p ..-->.. ..pi../sup plus-or-minus/p..gamma.. at 18 photon angles for 298-MeV incident pions. At all angles, the photon spectrum falls monotonically with increasing E/sub gamma/, and lacks the predicted structure due to the ..delta.. (1232) resonance. The soft-photon approximation agrees with the data for E/sub gamma/ < 50 MeV only. For higher E/sub gamma/, the simple external-emission-dominance calculation provides an acceptable but imperfect description of all of results. (AIP)
