摘要：

Data on the reaction gamma p -> p pi(0)pi(0) were taken with the CBELSA/TAPS experiment at ELSA where linearly polarized photons impinged on a transversely polarized butanol target. Target asymmetries and double polarization observables were extracted and entered the BnGa-PWA. Systematic differences in the branching ratios of N* and Delta* resonances hint at the internal structure of these states.
