Nuclear structure investigation of some neutron-rich halo nuclei

Abstract

The ground state proton, neutron and matter densities, the corresponding rms radii and charge form factors of a dripline nuclei 6He, [Formula: see text]Li, [Formula: see text]Be and [Formula: see text]Be have been studied via a three–body model of [Formula: see text]. The core–neutron interaction takes the form of Woods-Saxon (WS) potential. The two valence neutrons of 6He, [Formula: see text]Li and [Formula: see text]Be interact by the realistic interaction of ZBMII while those of [Formula: see text]Be interact via the realistic interaction of VPNP. The core and valence (halo) density distributions are described by the single-particle wave functions of the WS potential. The calculated results are discussed and compared with the experimental data. The long tail performance is clearly noticed in the calculated neutron and matter density distributions of these nuclei. The structure of the two valence neutrons in 6He, [Formula: see text]Li and [Formula: see text]Be is found to be mixed configurations with dominant [Formula: see text] while that for [Formula: see text]Be is mixed configurations with dominant ([Formula: see text]. The analysis of the present study supports the halo structure of these nuclei.
