    "abstract": "Coherent eta photoproduction on the deuteron is studied in the $S_{11}$\nresonance region neglecting eta rescattering and two-body processes. For the\nelementary reaction on the nucleon, we have considered the dominant\n$S_{11}(1535)$ resonance and as background the nucleon pole terms as well as\n$\\rho$ and $\\omega$ meson exchange. We have studied the influence of different\nchoices for the neutron resonance amplitude, different prescriptions for fixing\nthe invariant mass of the resonance amplitude and different methods for\nderiving the elementary production amplitude for an arbitrary reference frame.",
