Nuclear Structure Studies on Exotic Nuclei by Light-Ion Induced Direct Reactions with Stored Radioactive Beams — •Peter Egelhof — Gesellschaft für Schwerionenforschung mbH (GSI), D-64291 Darmstadt

The experimental conditions at the future facility FAIR will provide unique opportunities for nuclear structure studies on nuclei far off stability, and will allow reaching new regions in the chart of nuclides of high interest for nuclear structure and astrophysics. In particular, the predicted luminosities will allow for the investigation of direct reactions with stored and cooled radioactive beams at internal H, He, etc. targets of the storage ring NESR. This technique enables high resolution measurements down to very low momentum transfer and provides a gain in luminosity from accumulation and recirculation of the radioactive beams. A brief overview on the research objectives will be given.

The design of a complex detector setup, including a detector for recoiling target-like reaction products and gammas, surrounding the internal target, as well as a forward detector for fast ejectiles and beam-like reaction products, is presently investigated by the EXL collaboration with the aim to provide a highly efficient, high resolution universal detection system, applicable to a wide class of reactions. Results of a design study and the present status of the project are presented.
