%0 Journal Article %T Baryon Spectroscopy - Recent results from the Crystal Barrel Experiment at ELSA -* %A Schmidt C. %J EPJ Web of Conferences %D 2010 %I %R 10.1051/epjconf/20100303002 %X To understand the spectrum and the properties of baryon resonances, the CBELSA/TAPS experiment investigates the photoproduction o the nucleon using linearly, circularly polarized or unpolarized photons impinging on a polarized or unpolarized target. Preliminary results on rst double polarization observables have been obtained for the reactions $vec{gamma}{p}$ ¡ú p¦Ð0 and $vec{gamma}{p}$ ¡ú p¦Ç using both circular and linear polarized photons on a longitudinally polarized target. This data will nally provide important information for the partial wave analyzes used to extract the resonances from the data. %U http://dx.doi.org/10.1051/epjconf/20100303002
