NEUTRAL PION PHOTOPRODUCTION ON THE DEUTERON

Large-angle cross sections for γd→π0d are systematically measured in the photon energy range between 500 and 1000 MeV. A good fit is obtained by use of a Glauber-model calculation which includes the dibaryon resonances F33(2.26) and G41(2.51), but the fit has an unusual nature in the role of resonance and nonresonance contributions.

Pi0 photoproduction from complex nuclei

Meyer, W.T. ; Browman, A. ; Hanson, K. ; et al.

The photoproduction yields of π0 mesons from D2, Be, C, Al, Cu, Ag, and Pb targets have been measured at peak bremsstrahlung energies of 4.25, 5.6, 7.8, and 9.6 GeV. The A dependence of π0 photoproduction is found to be almost independent of energy in this range in contrast to vector-meson dominance predictions.
