Clustering and Correlations in Neutron Haloes

Abstract

In the present paper clustering and correlations within halo systems is explored. In particular, the application of neutron-neutron interferometry and Dalitz-plot type analyses is presented through the example provided by the dissociation of 14Be. A novel approach for producing and detecting bound neutron clusters is also described. The observation of some 6 events with characteristics consistent with the liberation of a multineutron cluster in the breakup of 14Be -- possibly in the channel 10Be+4n -- is discussed.
