Abstract: 
New high-precision measurements of p((gamma)over-right-arrow, pi) and p((gamma)over-right-arrow, gamma) cross sections and beam asymmetries have been combined with other polarization ratios in a simultaneous analysis of both reactions. Compton scattering has provided two important new constraints on the photo-pion amplitude. The E2/M1 mixing ratio for the N right-arrow Delta transition extracted from this analysis is EMR=-3.0%-/+0.3(stat+sys)-/+0.2(model).
