Photoproduction of Mesons off Light Nuclei

During the last few years photoproduction of mesons off light target nuclei ((2)H, (3)He, (7)Li) has been systematically studied at the tagged photon beams of the Bonn ELSA accelerator and the Mainz MAMI accelerator. The experiments used the combined Crystal Barrel/TAPS setup in Bonn and the Crystal Ball/TAPS setup in Mainz. Most measurements investigated meson photoproduction off the neutron for many different reaction channels in order to establish the iso-spin structure of electromagnetic resonance couplings. This project used mostly deuteron targets. The measurements with the He and Li targets aimed at the search for eta-mesic nuclei and hadron in-medium properties.
