Studies of Light Unbound Nuclear Systems — •Yuliya Aksyutina for the S245 collaboration — Gesellschaft fur Schwerionenforschung (GSI), D-64291 Darmstadt

The results of an experiment performed at the SIS-FRS facility (GSI, Darmstadt, Germany) with relativistic beams of ⁸He, ¹¹Li and ¹⁴Be impinging on a liquid hydrogen target will be discussed. The experimental setup, consisting of the neutron detector LAND, the dipole spectrometer ALADIN and different types of tracking detectors, allows for a reconstruction of the momentum vectors of all reaction products in coincidence. The main goals of this experiment are twofold. The collected data provides information on the structure of the drip-line nuclei ⁸He, ¹¹Li, ¹⁴Be and on the reaction mechanisms of these nuclei using a liquid hydrogen target. Futhermore, studies of unbound, exotic nuclear systems, which result from final state interactions between the different reaction products are performed. The observed systems are ⁷He, ⁹He, ¹⁰He, ¹⁰Li, ¹²Li, ¹³Li and ¹³Be. The talk is devoted to a discussion of results obtained for observed resonances and the physics interpretation of the data.
