Abstract
By extending the dynamical coupled-channels analysis performed in our previous work [Phys. Rev. C 88, 035209 (2013)] to include the available data of photoproduction of mesons off neutrons, the transition amplitudes for the photoexcitation of the neutron-to-nucleon resonances, , at the resonance pole positions are determined. The combined fits to the data for both the proton- and neutron-target reactions also revise our results for the resonance pole positions and the transition amplitudes. Our results allow an isospin decomposition of the transition amplitudes for the isospin resonances, which is necessary for testing hadron structure models and gives crucial inputs for constructing models of neutrino-induced reactions in the nucleon resonance region.
