Nuclear physics with stored highly-charged radioactive ions — •Yuri Litvinov — GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt — Max-Planck Institut für Kernphysik, Heidelberg

Investigations with stored highly-charged radionuclides are presently possible at two storage ring facilities. These facilities are the experimental storage ring ESR at GSI in Germany and the cooler-storage ring CSRe at IMP in China.

Storage ring mass spectrometry is a powerful tool to address rare nuclear species with tiny production rates. Large-scale explorations of the nuclear mass-surface have been done in the last years providing a vast information for nuclear structure investigations.

Beta-decay of highly-charged ions can presently be only studied with storage rings. Such measurements are of direct importance in nuclear astrophysics, since in hot stellar environments the atoms are highly-ionized. Another important reason is that the decays of well-defined quantum systems, such as one-electron ions, where the interactions with other bound electrons are excluded, can be investigated.

New experiments are inevitably connected with new technical developments. For instance, a novel highly-sensitive resonant Schottky pick-up detector has been commissioned in the ESR and CSRe.

The physics motivation, the techniques, recent experiments, and the main results will be discussed. Plans for future experiments at the ESR, CSRe as well as at the future FAIR facility will be outlined.
