Abstract

Observables for the , processes are calculated throughout the resonance energy region using the single isobar model without background. The connection between invariant photoexcitation amplitudes of the resonances on neutrons and protons are calculated. The results are discussed in terms of a comparison with experimental data and calculations performed by other authors.
