NUCLEAR SPECTROSCOPY STUDIES AT GSI -- FROM RISING TO HISPEC/DESPEC.

Nuclear spectroscopy using radioactive isotope beams requires dedicated set-ups. At the SIS/FRS facility at GSI exotic beams at relativistic energies were employed for Coulomb excitation and secondary fragmentation experiments with the fast beam RISING set-up. Shell evolution far off stability, pn-pairing, symmetries and nuclear shapes were studied in nuclei ranging from 36Ca to 136Nd. In another Ge-detector configuration a series of g-factor experiments was performed. Recently the compact detector arrangement of RISING -- providing about 15% full energy efficiency -- went into operation. Seniority isomers in medium heavy nuclei at the proton drip line have been investigated as well as new isomers found in neutron rich nuclei, e.g. 204Pt. Most recently the decay properties of 100Sn were investigated successfully. At future FAIR/GSI the Super-FRS facility within the NUSTAR project will provide an enormously enlarged variety of exotic beams. To fully exploit these beams the HISPEC/DESPEC project aims to develop, build and operate optimized experimental set-ups. Based on the experience with RISING novel particle identification and tracking detectors will be employed. For in-beam γ detection AGATA detectors are foreseen as well as a dedicated compact Ge tracking and imaging array for decay experiments. Well before the Super-FRS facility will become operational, detectors developed for HISPEC/DESPEC will be commissioned and employed for experimental campaigns within the PRESPEC project at the FRS facility at GSI.
