[en] The chiral constituent quark model is applied to predict the magnetic M1 and electric E2 amplitudes of the Δ↔γN transition. It is found that the one-meson-exchange quark-quark potential due to the chiral fields enhances the E2/M1 ratio by a factor of about 2. The predicted M1+ amplitude and the E2/M1 ratio ≅-1.0% are within the range determined from a recent analysis of the data of pion photoproduction. copyright 1997 The American Physical Society
