Description

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 pa0(980) as intermediate states. A partial-wave analysis suggests that the reaction proceeds via formation of six Δ -resonances, Δ(1600)P33, Δ(1920)P33, Δ(1700)D33, Δ(1940)D33, Δ(1905)F35, Δ(2360)D33, and two nucleon resonances N(1880)P11 and N(2200)P13, for which pole positions and decay branching ratios are given.
