Probing Few-Body Correlations in Light, Neutron-Rich Nuclei

Abstract.

 The advent of secondary beams of very neutron-rich nuclei gives access to the investigation of correlations in the few-neutron system. Results of different experiments undertaken at GANIL with ⁶He, ¹¹Li, and ¹⁴Be beams are discussed. These nuclei exhibit a two-neutron halo, in which the correlations between the two neutrons provide the stability of the A-body system. A new technique aiming to explore the possible binding of systems of more than two neutrons will also be presented, together with very preliminary results that suggest the particle stability of ⁴ n.
