Influence of diffuseness of nuclear potential on the neutron halo structure of Zr isotopes near the neutron drip line

The single-particle characteristics of the halo structure ofZr isotopes near the neutron drip line were calculated within the dispersive optical model. The influence of the increase in the diffuseness of the nuclear Hartree–Fock type potential on the root-mean-square radii of halo states and their populations was considered. A significant difference was shown between the number of neutrons in halo states and in the r > 12 fm region, where there is no spatial correlation of neutrons with the core of nucleus.
