Abstract:  Neutron-rich nuclear systems reveal particular phenomena such as shell evolution with proton-neutron asymmetry, halos and neutron skins. Large efforts are being made worldwide to reach the most neutron-rich nuclei and investigate how their structure differ from stable ones, leading to stringent tests for the predictive power of state-of-the art nuclear structure models. In this seminar, the most recent results from a three-year gamma-spectroscopy campaign at the Radioactive Isotope Beam Factory (RIBF) of RIKEN in Japan, today's most powerful accelerator to produce neutron-rich nuclei. The concept of PUMA (antiProton Unstable Matter Annihilation), a new project at CERN, will be introduced. PUMA aims at using low-energy antiprotons to probe the tail of the matter density of neutron rich nuclei. It should provide a new way to investigate the emergence of neutron skins and halos.
