Study of the reaction γp → pπ0η

The reaction γp → pπ0η has been studied with the CBELSA detector at the tagged photon beam of the Bonn electron stretcher facility. The reaction shows contributions from Δ+(1232)η , N(1535)+π0 and pa 0(980) as intermediate states. A partial-wave analysis suggests that the reaction proceeds via formation of six Δ -resonances, Δ(1600)P 33 , Δ(1920)P 33 , Δ(1700)D 33 , Δ(1940)D 33 , Δ(1905)F 35 , Δ(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.
