Photoproduction of eta-mesons from light nucleiAbstract: In a series of experiments coherent and quasifree eta-photoproduction from light nuclei (4He, 3He, 2H) was investigated with the TAPS-detector at the Mainz MAMI-accelerator. The experiments were motivated by two different subjects: the determination of the isospin structure of the electromagnetic excitation of the S11(1535) resonance and the study of the eta-nucleon and eta-nucleus interaction at small momenta. The results for the deuteron and 4He are summarized and first preliminary results for 3He are presented.
