N(1520)3/2−Helicity Amplitudes from an Energy-Independent Multipole Analysis Based on New Polarization Data on …

New data on the polarization observables T P and Hfor the reaction \ensuremath{\gamma}p\ensuremath{\rightarrow}p{\ensuremath{\pi}}^{0}are reported. The results are extracted from azimuthal asymmetries when a transversely polarized butanol target and a linearly polarized photon beam are used. The data were taken at the Bonn electron stretcher accelerator ELSA using the CBELSA/TAPS detector. These and earlier data are used to perform a...
