Coulomb excitation and Transfer Experiments at REX-ISOLDE^* — •Thorsten Kröll — TU Darmstadt — TU München

The aim of recent research in nuclear physics is the understanding of the structure of nuclei far off stability. In this contribution, the highly successful experimental programme in this field based on the use of post-accelerated radioactive ion beams (RIBs) obtained from the REX-ISOLDE facility at CERN will be presented. The beams utilised range from Li up to Rn comprising more than 60 isotopes from both the proton- and neutron-rich side of the nuclear chart.

The research programme covers a wide range of topics like the evolution of magic numbers, the intriguing phenomenon of shape coexistence, and reactions of astrophysical interest. The experimental methods are “safe” Coulomb excitation and one- and two-nucleon transfer (or capture) reactions investigated by high-resolution γ-ray spectroscopy with the MINIBALL spectrometer as well as particle spectroscopy with a Si detector array.

The status and recent results of the programme as well as perspectives for future experiments and the upgrade to HIE-ISOLDE will be presented and discussed.
