摘要：

The ratio of electric quadrupole (E2) and magnetic dipole (M1) photodecay amplitudes for the DELTA(1232) is determined. This extraction is based on direct multipole analyses of the existing database for the pion photoproduction reaction. Our values are in qualitative agreement with the results of Davidson, Mukhopadhyay, and Wittman. We compare and contrast our results with other recent determinations of this ratio.
