Microscopic multicluster model of9,10,11Li

Abstract

A microscopic cluster model assuming $\alpha$-, triton, and single-neutron clusters is applied to the halo nucleus ${}^{11}\mathrm{Li}$ and to its subsystems ${}^9\mathrm{Li}$ and ${}^{10}\mathrm{Li}.$ This model is consistent with an earlier successful description of ${}^{7,8,9}\mathrm{Li}.$ The results for the energies, radii, and other properties of ${}^{11}\mathrm{Li}$ are satisfactory. The binding of ${}^{11}\mathrm{Li}$ receives comparable contributions from p- and s-wave single-particle states. The two-neutron halo of ${}^{11}\mathrm{Li}$ is confirmed to be prominent although it is reduced by core distortion.
