Photoproduction of Baryon Resonances First Results of the Crystal Barrel Experiment at ELSA

J. Junkersfeld

Photoproduction data on various final states involving neutral mesons have been taken by the CB-ELSA-experiment at the Electron Stretcher Accelerator ELSA (Bonn). The data show clear structures due to resonance production. Evidence for successive decays of high-mass nucleon resonances via  \Delta (1232)\pi 0, \Delta (1232)\eta and N(1535)S11\pi 0 have been observed. There is evidence for production of  {a0(980)-mesons} in their \pi 0\eta decay.
