Abstract

The D3/2 nature of the second resonance in neutral single pion photoproduction, γ+p→p+π0, suggested by Peierls, has been confirmed by additional experimental observations of the polarization of the recoil proton over a range of photon energies. The photon energy dependence of the polarization at 90° c.m. is in substantial disagreement with alternative models suggested by Stoppini and Pellegrini, and Landovitz and Marshall if the observed angular distributions are also considered. An experimental method using nuclear emulsion as scatterer-detector, in conjunction with a magnetic spectrometer, is shown to have both good energy resolution and reasonable counting rate.
