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, γ) 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).
