| Abstract: | Differential and total cross-sections for photoproduction of γp→pπ 0 ω and γp→Δ + ω were determined from measurements of the CB-ELSA experiment, performed at the electron accelerator ELSA in Bonn. The measurements covered the photon energy range from the production threshold up to 3GeV. |
