Meson-Photoproduction with the Crystal-Barrel Detector at Elsa

The photoinduced production of neutral mesons off protons has been studied with the Crystal-Barrel-detector at the electron stretcher facility ELSA. First data demonstrate that reactions with multi-photon final states can be reconstructed with high efficiency. Preliminary results on γp → pπ⁰π⁰ and γp → pπ⁰η show evidence for successive decays of high mass states through different intermediate resonances.
