Abstract:
Photoproduction of pi(0)-mesons was studied with the Crystal-Barrel detector at ELSA for incident energies from 300 MeV to 3 GeV. Differential cross-sections d sigma/d Omega, d sigma/dt, and the total cross-section are presented. For E (gamma) < 3 GeV, the angular distributions agree well with the SAID parametrization. At photon energies above 1.5 GeV, a strong forward peaking indicates t-channel exchange to be the dominant process. The rapid variations of the cross-section with energy and angle indicate production of resonances. An interpretation of the data within the Bonn-Gatchina partial-wave analysis is briefly discussed.
