Abstract

On the basis of the dynamical model for meson photoproduction on nucleons, it is shown that only eight broad resonances (of width in excess of 120 MeV), of which two belong to the class of missing resonances, are required for reproducing experimental data from the threshold for the reaction γp → ηp to the photon energy of 3 GeV.
