Abstract
The recently observed weakly bound provides a stringent theoretical constraint on the neutron drip line. We studied the properties of drip-line nuclei around with the Hartree-Fock-Bogoliubov method and various Skyrme interactions. We adopted the extended 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 is weakly bound and is less weakly bound. and could barely exist. We also demonstrated the deformed halo properties of . 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.
