Nuclear Structure Addressed At GSI/RISING

• Nuclear structure spectroscopy studies at GSI recently gained increased momentum within a broad international community with the installation of the Rare Isotopes Spectroscopic INvestigation at GSI (RISING) project. A wide range of physical phenomena has been addressed by high-resolution in-beam gamma-ray spectroscopy experiments with radioactive beams. Relativistic radioactive beams are implanted and their subsequent. and beta decay is investigated. Within this "stopped beam campaign" germanium detectors were arranged in a close geometry around the passive stopper or an array of DSSSD detectors. The exceptionally high gamma-ray efficiency of that configuration made it possible to identify decays of excited or ground states of nuclei which have not been observed before. The results discussed here include the astrophysically relevant shell structure of N=82 isotones, N=Z nuclei around Ni-54, and proton drip-line nuclei below Sn-100. The experimental data are compared to the results of large scale shell-model calculations using various sets of realistic residual two-body interaction.
