Study of the reaction gamma roh -> roh pi0eta
Abstract
The reaction gammaroh -> rohpi0eta 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)+etasigma and pa0(980) as intermediate states. A partial-wave analysis suggests that the reaction proceeds via formation of six Delta-resonances, Delta(1600)P33, Delta(1920)P33, Delta(1700)D33, Delta(1940)D33, Delta(1905)F35, Delta(2360)D33, and two nucleons resonances N(1880)P11 and N(2200)P13, for which pole positions and decay branching rations are given.
