Lithium isotopes within the ab intio no-core full configuration approach

Abstract

We perform no-core full configuration calculations for the Lithium isotopes, 6Li, 7Li, and 8Li with the realistic nucleon-nucleon interaction JISP16. We obtain a set of observables, such as spectra, radii, multipole moments, transition rates, etc., 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 MeV, 0.7 MeV, and 1.0 MeV for 6Li, 7Li, 8Li respectively. Magnetic moments are well-converged and agree with experiment to within 20%.
