摘要：

An effective Lagrangian calculation of pion photoproduction including all nucleon resonances up to root s = 1.7 GeV is presented. We compare our results with recent calculations and show the influence of different width parametrizations and off-shell cutoffs on the photoproduction multipoles. We determine the electromagnetic couplings of the resonances from a new fit to the multipole data.
