        "abstract": "The D3/2 nature of the second resonance in neutral single pion photoproduction, \u03b3+p\u2192p+\u03c00, 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\u00b0 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.",
