Photoproduction of single neutral pions from hydrogen at 60° in the 600-1100 Mev region

Abstract

In a recent experiment Cortellessa and Reale (1) measured the differential cross section for the process γ + p → π°+ p in the neighborhood of the second resonance at a center-of-mass angle for the neutral pion of 57°. Their results, obtained with a proton telescope in coincidence with a lead glass Cerenkov counter used to detect one of the π° decay photons, are considerably different from those which had been reported previously.
