Nuclear spectroscopy using radioactive isotope beams requires dedicated set-ups. State-of-the-art Ge arrays recently started to provide valuable γ spectroscopic data. 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. The observation of a I = 27 ħ state demonstrated that high spin states can be reached in massive fragmentation reactions. This and the large sensitivity of relativistic in-beam experiments opens a rich ground for advanced nuclear structure studies. Combining RISING with AGATA γ-tracking detectors and improved particle detection is planned for future experimental investigations.
