摘要：

Resonance couplings for the resonant states P33(1232), P11(1440), D13(1520), and S11(1535) are extracted from a recent multipole analysis of pion photoproduction data. We calculate photoproduction residues at the resonance pole in the complex plane for these amplitudes, in addition to the resonance widths at the on-shell resonance energies. © 1990 The American Physical Society.
