Hyperspherical three body calculation for exotic halo nuclei

In the present work investigate the bound state properties along with some other interesting features of exotic halo nuclei- ¹⁴Be, ¹⁷B, ¹⁹ B, ²²C etc in the framework of hyperspherical harmonics expansion method (HHEM). We assume a few-body (two- and three-body) model consisting of a structureless nuclear core plus one or two valence nucleon(s) forming a far extended low density tail by the quantum mechanical tunneling of the last one or two nucleon(s)
