Clustering and correlations at the neutron dripline

Some recent experimental studies of clustering and correlations within very neutron-rich light nuclei are reviewed. In particular, the development of the novel probes of neutron-neutron interferometry and Dalitz-plot analyses is presented through the example of the dissociation of the two-neutron halo system 14Be. The utility of high-energy proton radiative capture is illustrated using a study of the 6He(p, ) reaction. A new approach to the production and detection of bound neutron clusters is also described, and the observation of events with the characteristics expected for tetraneutrons (4n) liberated in the breakup of 14Be is discussed. The prospects for future work, including systems beyond the neutron dripline, are briefly outlined. To cite this article: N. Orr, F.M. Marqués, C. R. Physique 4 (2003).


Nous présentons une revue des résultats récents concernant les corrélations et le phénomène d'agrégation à la limite de liaison des neutrons. Nous mettons l'accent sur les nouvelles observables telles l'interférométrie de neutrons et les analyses à la Dalitz que nous illustrons sur le système 14Be qui a un halo de deux neutrons. Nous illustrons l'importance des réactions de capture radiative de proton à haute énergie grâce à la réaction 6He(p, ). Une nouvelle méthode pour détecter d'éventuels agrégats de neutrons, est aussi présentée. Des résultats plaidant en faveur de l'observation d'un quadrineutron (4n) libéré lors de la cassure d'un 14Be sont discutés. De futures expériences allant même au-delà de la limite de liaison neutrons sont proposées. Pour citer cet article : N. Orr, F.M. Marqués, C. R. Physique 4 (2003).
