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 photopion amplitude. The E2/M1 mixing ratio for the N --> delta transition extracted from this analysis is [-3.0 +/- 0.3(stat + syst) +/- 0.2 (model)]%. Both data and analysis of this work are in conflict with recent results from Mainz.
