Polarization Observables of the Reaction γp→η'p Near Threshold

In the isobaric model of photoproduction of η'-mesons on protons, reproducing well the experimental cross sections for photon energies from 1500 to 2500 MeV and the Σ-asymmetry of this reaction near its threshold, various polarization observables of this reaction have been calculated in the energy range near its threshold in order to stimulate future experiments.
