英文摘要: The ground-state properties of Ca isotopes far from stability line were systematically studied using the Skyrme-Hartree-Fock model. The shell effects on the binding energy and two neutron separation energy are discussed. The isospin dependency of the nuclear radii and nucleon density distributions and the shell effects on these properties are also studied. It is shown that the neutron magic number affects the width of nuclear surface and the nucleon density distributions beyond the nuclear surface. The change of proton rms radii R-rms with neutron number excess I =(N-Z)/A follows R-rms = root3/5 (1 + alphaI + betaI(2))r(p)Z(1/3). The effect of the centrifugal potential on the nuclear density in the outer-reach of nuclear surface is clearly shown.
