Abstract

The reaction gamma p -< p pi(0)eta has been studied with the CBELSA detector at the tagged photon beam of the Bonn electron stretcher facility. The reaction shows contributions from Delta(+)(1232)eta, N(1535)(+) pi(0) and pa(0)(980) as intermediate states. A partial-wave analysis suggests that the reaction proceeds via formation of six Delta-resonances, Delta(1600)P-33, Delta(1920)P-33, Delta(1700)D-33, Delta(1940)D-33, Delta(1905)F-35, Delta(2360)D-33, and two nucleon resonances N(1880)P-11 and N(2200)P-13, for which pole positions and decay branching ratios are given.
