摘要：

Asymptotic properties of the neutron mean potential are studied using the Skyrme-Hartree-Fock potential and Wood-Saxon potential in the stable nucleus Ca-48 and the neutron-rich nucleus Ca-60. 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 Ca-48. But for Ca-60 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 Ca-60 as well as the surface part.
