摘要：

We investigate the role of the + mass and the magnetic dipole coupling parameters in the extraction of the ratio of electric quadrupole to magnetic dipole amplitudes (EMR) in the +r transition. We show that existing data on single-pion photoproduction do not allow as wide a range (5%) of values for the EMR as concluded in a recent paper by Slaughter and Oneda [Phys. Rev. D 49, 323 (1994)]. © 1995 The American Physical Society.
