Abstract

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. Measurements have been made of the cross-sections for neutral meson photoproduction from protons at angles in the forward hemisphere for photon energies near 911, 1182, and 1390 MeV. The experimental method consists of detecting the decay gamma-rays of the neutral meson in two pb-glass total absorption Cerenkov counters. The results agree very well with the existing data where the same points have been measured. The striking feature of the angular distributions at 1182 and 1390 MeV is the small 0[degree] cross-section and the peak near 30[degrees] to 40[degrees] in the CMS. Using as a model for the cross-section calculation a vector meson X[degrees] exchange plus background, we find the product [...] for M[subscript X] = 788 MeV. Fits made without the vector meson pole are not inconsistent with a resonance model for the cross-section.
