Abstract
Photoproduction of neutral pions has been studied with the CBELSA/TAPS detector in the reaction for photon energies between 0.85 and 2.50 GeV. The mesons are observed in their dominant neutral decay mode: . For the first time, the differential cross sections cover the very forward region, . A partial-wave analysis of these data within the Bonn-Gatchina framework observes the high-mass resonances (2190), (2080), and (2070).
