Nuclear structure studies at GSI attracted recently increased interest for the results of present activities as well as for the future project FAIR. A broad range of physics phenomena can be addressed by high-resolution in-beam \gamma -ray spectroscopy experiments with radioactive beams offered within the Rare Isotopes Spectroscopic INvestigation at GSI (RISING) project. It combined the EUROBALL Ge-Cluster detectors, the MINIBALL Ge detectors, the HECTOR-BaF detectors, and the fragment separator FRS. The secondary beams produced at relativistic energies were used for Coulomb excitation or secondary fragmentation experiments to study projectile like nuclei by measuring de-excitation photons. The first results of the ``fast beam campaign'' is discussed in comparison to various shell model calculations. The discussion focuses on the N=32,34 sub-shell closure based on neutron rich Cr isotopes. Alternatively, the relativistic radioactive beams, both in their ground and isomeric states, were implanted and their decay could be investigated. The ``stopped beam campaign'' has started in October 2005 with a series of g-factor measurements. It continued from February 2006 with the next configuration and the main goal of identification of new isomers and angular momentum population in fragmentation reactions.
