Abstract

The recently observed weakly bound Na39 provides a stringent theoretical constraint on the neutron drip line. We studied the properties of drip-line nuclei around Na39 with the Hartree-Fock-Bogoliubov method and various Skyrme interactions. We adopted the extended SkMext1* parametrization which can properly describe two-neutron separation energies of oxygen and fluorine isotopes and deformations at the center of “island of inversion.” Systematic calculations of drip lines of O, F, Ne, Na, Mg, and Al isotopes have been performed. We infer that Mg42 is weakly bound and Al45 is less weakly bound. Mg44 and Al47 could barely exist. We also demonstrated the deformed halo properties of Na39. Our studies could be valuable for experimental explorations of drip-line nuclei in the forthcoming Facility for Rare Isotope Beams (FRIB) and other rare-isotope beam facilities.
