Search for ω-mesic nuclei — •Karoly Makonyi and Stefan Friedrich — II. Physikalisches Institut, Heinrich-Buff-Ring 16, 35392 Giessen

The existence and properties of ω-mesic nuclei are being studied with the tagged photon beam of the ELSA accelerator in Bonn. The combined setup of the Crystal Barrel and MiniTAPS detector systems, which form a 4π electromagnetic calorimeter, was used for detecting the possible ω-mesic states via the ω→π+γ decay mode and the conversion (ω+NN*→ π0+N) mode. The recoiling proton of the γ+p→ω+p reaction was identified with an aerogel Cherenkov detector and the forward angle spectrometer MiniTAPS. A first experiment on a carbon target has been performed as well a reference measurement on LH2. The status of the analysis will be presented.
