Abstract
We present a nucleon resonance analysis by simultaneously considering all pion- and photon-induced experimental data on the final states gammaN, piN, 2piN, etaN, KLambda, KSigma, and omegaN for energies from the nucleon mass up to roots=2 GeV. In this analysis we find strong evidence for the resonances P-31(1750), P-13(1900), P-33(1920), and D-13(1950). The omegaN production mechanism is dominated by large P-11(1710) and P-13(1900) contributions. In this second part we present the results on the photoproduction reactions and the electromagnetic properties of the resonances. The inclusion of all important final states up to roots=2 GeV allows for estimates on the importance of the individual states for the GDH sum rule.
