“…With the advent of the quark model I- [1][2][3][4], data on the photo-production of mesons have been used in determining the properties of electro-magnetic couplings of the lower-lying nuclear resonances [5,6] and this has led to a revival of interest in the determination of n~ cross-sections in the resonance region. In this paper, the final results of recent measurements of these cross-sections in the pion c.m.…”

Abstract. Some cross-sections for the photo-production of ~z~ from hydrogen for pion c.m. angles in the range 60~ ~ are presented. The data have been obtained by measuring proton yields from a hydrogen target, thus permitting separation of single-pion production from the strong background caused by double-pion production. The values, which extend from 360 to 938 MeV, show reasonable agreement with the results of a recent phase-shift analysis.
