Abstract

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 photo-decay amplitudes. This agrees with results found in Compton scattering. Our values are also in good agreement with a previous RPI 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 good agreement with recent the Mainz value.
