To unambiguously identify baryon resonances the measurement of polarization observables is of large importance. With the Crystal Barrel/TAPS experiment, located at the ELSA accelerator facility in Bonn, Germany, polarization observables have been determined using a linearly polarized photon beam impinging on a liquid hydrogen target. In this talk an overview of these measurements will be given and new results on the polarization observables IS
will be presented for the reaction γp → pπ0
. A comparison of the results with predictions of the Bonn-Gatchina-partial wave analysis shows that the data provide new constraints for the extraction of baryon resonances. In addition, invariant mass distributions and Dalitz plots, indicating cascade-decays via different excited states will be discussed.
The work was performed by the CBELSA/TAPS Collaboration at the Helmholtz-Institut fuer Strahlen- und Kernphysik (University of Bonn).
