Halo Formation in Heavy Sodium Isotopes and Orbit Inversion

This paper investigates the impact of inverting the p and f shell-model orbits on the formation of halo structures in neutron-rich sodium isotopes. It uses theoretical models to explore the phenomenon, focusing on isotopes like 34, 37, and 39Na. The research is significant because it contributes to our understanding of nuclear structure, particularly in exotic nuclei, and how shell structure influences halo formation. The study also suggests a method (electric dipole response) to experimentally probe these structures.
