摘要：

We have updated our multipole analyses to incorporate new data from the low-energy and Delta resonance regions. We note a slight decrease in our estimate of the Delta photodecay amplitudes. This agrees with results found in Compton scattering. Our values are also in good agreement with another previous determination. We have reexamined our determinations of the E2/M1 ratio at the resonance energy and at the pole. We find an E2/M1 ratio (at the pole) which is in go od agreement with the recent Mainz value.
