The Three-Body Structure of 2n and 2p Halo Nuclei
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2018, Vol 5, Issue 2
Abstract
A three-cluster model developed for ternary fission studies has been applied for the first time to study the three-body structure of 2n and2p halo nuclei. For the experimentally known 2n, 2p halo nuclei, all possible ternary fragmentation potential energy surface (PES) iscalculated. The two-body breakup reported earlier, clearly indicated a strong minimum in the PES corresponding to 1n/1p and/or 2n/2p clusterplus core configuration. However, the present calculations of PES reveal that the three- body breakup does not result always with 2n and/or 2p as a cluster. A 1n and/or 1p cluster along with the core is initially formed, and then the core loses one nucleon to make either a 2n plus core or 2p plus core structure. The results are substantiated with the calculations of preformation probability calculated within quantum mechanical fragmentation theory.
