摘要The pure-neutron-matter together with the neutron skin or halo in Ca isotopes is studied using the Skyrme-Hartree-Fock model. It is shown that the pure-neutron-matter thickness depends not only on the Fermi levels of the neutrons, but also on the orbital angular momentum of the valence neutrons. A new definition for the thickness of pure-neutron-matter is proposed. Particles in classically forbidden area are also studied. The number of neutrons in the classically forbidden area increases with mass number A, because of the increase in the number of neutrons occupied in the weaklybound open shell. The number of protons in the classically forbidden area, in contrast, decreases with mass number A, because the orbits of protons become more deeply bound. It is shown that the number of particles in the classically forbidden area can give information on the appearance of the halo or skin.
