Lithium isotopes within the<i>ab initio</i>no-core full configuration approach

Abstract

We perform no-core full configuration calculations for the lithium isotopes ${}^{6}$Li, ${}^{7}$Li, and ${}^{8}$Li with the realistic nucleon-nucleon interaction JISP16. We obtain a set of observables, including spectra, radii, multipole moments, and transition probabilities, and compare with experiment where available. We also present one-body density distributions for selected states. Convergence properties of these density distributions shed light on the convergence properties of one-body observables. We obtain underbinding by 0.5, 0.7, and 1.0 MeV for ${}^{6}$Li, ${}^{7}$Li, and ${}^{8}$Li, respectively. Magnetic moments are well converged and agree with experiment to within 20$%$.
