Abstract

η-meson photoproduction on the proton was studied by using the effective Lagrangian approach at the tree-level in energy range from treshold up to 1.87 GeV. Besides the Born and vector-meson terms, S11 (1535), S11 (1650) and D13 (1520), were included in the calculation of the transition amplitudes. The role of the D13 resonance was investigated according to the simple and complete formulation of the spin-3/2 propagator. The parameters were extracted from fitting to the experimental data consisting of differential cross sections from the Crystall Ball Collaboration at MAMI.
