AbstractAbstract
[en] A multipole analysis at low energies is combined with an amplitude analysis at higher energies through the constaints imposed by fixed-t dispersion relations in an attempt to fit simultaneously to the single-pion photoproduction data between threshold and 16 GeV. The photonic couplings of all well-established resonances below 2.5 GeV have been studied and the high-energy structure of the amplitudes examined. (Auth.)
