Summary:Title screen
Coherent η meson photoproduction on 4He and 12C is considered in the near-threshold region. The elementary η photoproduction operator includes contributions from the S11 (1535) and D13 (1520) resonances as well as t-channel vector meson exchange and the nucleon pole terms. Due to the suppression of the dominant S11 (1535) resonance for spin and isospin saturated nuclei, the reaction is mainly governed by ω exchange. Furthermore, the influence of Fermi motion and of different prescriptions for the choice of the invariant reaction energy WyN in the elementary amplitude is studied.
