Energy-dependent analysis of eta-meson photoproduction on protons and neutrons without background in the energy region up to 3.4 GeV

摘要

Observables for the γp → ηp, γn → ηn 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.
