Abstract / Description of output
Total and differential cross-sections for the reaction gamma p -> pi(0)eta p have been measured with the Crystal Ball/TAPS detector using the tagged photon facility at the MAMI C accelerator in Mainz. In the energy range E-gamma = 0.95-1.4 GeV the reaction is dominated by the excitation and sequential decay of the Delta(1700)D-33-resonance. Angular distributions measured with high statistics allow us to determine the ratio of hadronic decay widths Gamma(eta Delta)/Gamma pi S-11 and the ratio of the helicity amplitudes A(3/2)/A(1/2) for this resonance.
