Three-body halo nuclei in the hyperspherical harmonics methods

Abstract

Substantial progress has been made in the studies of loosely-bound nuclei, however there are many issues about the properties of these nuclei that have not been resolved yet. For example nuclear decay, nuclear reactions and nuclear structure remain open questions. Despite the large amount of information on proton and neutron halo systems, there are structural similarities and di erences in these nuclei that are yet to be fully understood. The purpose of this study is to theoretically investigate structural properties of the light halo nuclei 8B, 6He, 6Li,6Be,9Be and 9B. In this study, these nuclei are treated as three-body systems interacting through standard potentials. The Faddeev equations for these potentials are solved using the hyperspherical harmonic methods. The ground-state energy, root-mean square radius and wavefunctions were calculated and the results obtained were compared with theoretical and experimental results reported in literature.
