摘要

A? three-cluster? model? developed? for? ternary? fission? studies? has?been?applied?for?the?first?time?to?study?the?three-body?structure?of?2n?and? 2p?halo nuclei. For the experimentally known 2n, 2p halo nuclei, all possible ternary fragmentation potential energy surface (PES) is calculated. The two-body breakup reported earlier, clearly indicated a strong minimum in the?PES?corresponding?to?1n/1p?and/or?2n/2p?cluster? plus?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.
