Physics with exotic nuclei at the Low-Energy-Branch of the Super-FRS — •C. Scheidenberger for the NUSTAR collaboration — GSI Darmstadt

The Low-Energy-Branch of the Super-FRS will provide high-intensity exotic nuclear beams of all elements for experiments with energies in the range (5...200)MeV/u, with stopped beams, and with accelerated beams (10...100)keV. Versatile and advanced instrumentation will provide ideal conditions for a broad experimental physics programme. The high-intensity beams will allow for new astrophysical studies relevant for a deeper understanding of the s-process. High-resolution gamma-ray spectroscopy will explore Coulomb excitations close to the barrier and nucleon transfer, deep-inelastic and compound reactions. Decay spectroscopy with stopped beams (alpha-, beta- and isomer-spectroscopy) of nuclei implanted in thin, active stoppers will benefit from small range straggling and thus allow for new opportunities in x-ray and electron spectroscopy. Accelerated beams will be available due to the use of a new hybrid system (in-flight separation, energy focusing, and stopping in a helium-filled stopping cell). The full experimental spectrum of modern low-energy radioactive-beam facilities, such as Penning traps, charge breeders (EBIS), electron-beam ion traps (EBIT), LASER spectroscopy will be used to study neutron rich nuclei. The opportunity to produce exotic nuclei and antiprotons at the same facility will allow for new experiments using this particular hadronic probe, for instance for the study of formation and properties of antiprotonic exotic nuclei.
