Abstract：
Asymptotic properties of the neutron mean potential are studied using the Skyrme-Hartree-Fock potential and Wood-Saxon potential in the stable nucleus ⁴⁸Ca and the neutron-rich nucleus ⁶⁰Ca . We find that the WS potential can reproduce pretty well compared to the SHF potential in the tail part as well as in the surface region for the stable nucleus ⁴⁸Ca.But for ⁶⁰Ca ,the WS potential shows a big difference in the tail part from the SHF potential. A corrected Wood-Saxon form is suggested to describe the neutron-halo feature in neutron-rich nuclei. We see that the potential of this form can give a good description of the long tail in ⁶⁰Ca as well as the surface part.
