Abstract

The differential cross section of the reaction γp → π 0p has been measured at the Deutsches Elektronen Synchrotron DESY, Hamburg, at a mean photon energy of 4.0 GeV in the four-momentum transfer range between t = −0.2 (GeV/ c) 2 and t = −1,2 (GeV/ c) 2 in steps of approximately 0.08 (GeV/ c) 2. The experiment was carried out in connection with the measurements of the photoproduction of π 0 mesons on deuterium, which were described in the preceding article. In the present paper the contributions arising from background reactions are discussed in more detail.
