Search for ω-mesic nuclei — •Karoly Makonyi — 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 facility at 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 possible decay mode of ω mesic state (ω+p→ N^*→π^∘+p). The recoiling proton of the γ+p→ω+p reaction was identified with an aerogel Cherenkov detector and by energy and time information. A first experiment on a carbon target has been performed. The status of the analysis will be presented.
