Recent Developments in Sensitive High-Resolution Laser Spectroscopy at ISOLDE-CERN

Bldg. 6008 Large Conference Room

Laser-spectroscopy techniques provide a powerful tool to obtain nuclear structure information on the ground state properties of exotic nuclei. These techniques allow to extract observables that are key for our understanding of the nuclear many-body problem; nuclear ground-state spins, electromagnetic moments, and changes in the root-mean square charge radii (rms) [1,2]. With the aim of expanding the experimental knowledge of these properties at extreme limits of the nuclear chart, where radioactive isotopes are produced at rates of only a few ion/s, new developments have been successfully demonstrated at ISOLDE-CERN [3,4]. In this seminar, we will discuss the latest results from sensitive high-resolution collinear laser spectroscopy, in addition to the future experimental programs focused on studying isotopes around doubly-magic nuclei. The relevance of these results, in connection with the recent developments in nuclear theory, will be presented.
