Summary:The predictive calculations of the single-particle halo structure in Zr isotopes near the neutron drip line have been carried out using the dispersive optical model. The influence of the expected increase in the diffuseness parameter of the nuclear potential for neutron-excess nuclei on the mean square radii of halo states and their populations has been investigated. A significant difference has been shown between the number of neutrons in halo states and the number of neutrons in the region fm where there is no spatial correlation between halo neutrons and the nuclear core.
