In-gas cell laser-based production and spectroscopy of exotic nuclei at the Super Separator Spectrometer S3.

The project aims to couple the Leuven Laser Gas Cell, developed at the Leuven Isotope Separator On Line (LISOL) project (Louvain-la-Neuve, Belgium) to the new Super Separator Spectrometer S3 to be built within the SPIRAL-2 project at GANIL, Caen, France. The combination of the high-intensity stable beams from the new accelerator LINAG at GANIL, the strong suppression of primary beam and unwanted isobars in S3, the fast and universal stopping in the gas cell, the selective resonant laser ionization and the high-resolution isobar separator will deliver high-quality beams of far unstable nuclei in selected regions of the nuvlear chart that are not available elsewhere. These beams will be used to determine the decay properties of these short-living nuclei only having half lives in the hundreds of milliseconds. Furthermore by scanning the frequency of the laser light, ground state properties such as magnetic dipole moments and charge radii will become accessible. The project focuses on two regions of the nuclear chart: the region around doubly-magic 100Sn and the region of heavy to superheavy elements.
