Probing few-body correlations in light, neutron-rich nuclei

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 He-6, Li-11, and Be-14 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.
