摘要：

Differential cross sections for the process pi(-)p-->gamman have been measured at Brookhaven National Laboratory's Alternating Gradient Synchrotron with the Crystal Ball multiphoton spectrometer. Measurements were made at 18 pion momenta from 238 to 748 MeV/c, corresponding to E-gamma for the inverse reaction from 285 to 769 MeV. The data have been used to evaluate the gamman multipoles in the vicinity of the N(1440) resonance. We compare our data and multipoles to previous determinations.
