Collapse of the N=28 shell closure in the newly discovered ³⁹Na nucleus and the development of deformed halos towards the neutron dripline

NUCLEAR STRUCTURE ³⁹Na; calculated S(n), single-neutron levels, J, π, quadrupole deformation, rms radius. ^{31,33,35,37,39,41}Na; calculated neutron density distributions. Pointed that ³⁹Na could be single nucleus with the coexistence of several exotic structures, including the quenched N=28 shell closure, Borromean structure, deformed halo, and between the core and the halo. Discussed the microscopic mechanisms behind the shape decoupling phenomenon and the development of halos towards dripline. Deformed relativistic Hartree-Bogoliubov theory in continuum.

Missed prediction of the neutron halo in ³⁷Mg

NUCLEAR STRUCTURE ^35,36,37Mg; calculated neutron density distributions, single-neutron energies, occupation probabilities using a microscopic and self-consistent way using the deformed relativistic Hartree-Bogoliubov theory in continuum; deduced the deformed p-wave halo characteristics of ³⁷Mg.
