使用三体模型和现实的二体势，我们研究了质子滴线附近的 18Ne 和 28S 原子核的性质。我们计算出了二质子的分离能、价质子的占据、物质的均方根半径和价质子。此外，还显示空间相关密度以反映两个价质子之间的相关性。根据我们的计算，18Ne的第一激发0+态很可能是晕态。关闭三体系统之间的库仑相互作用，我们得到了对应镜像核的二中子分离能和价中子构型。结果表明，三体模型适合描述一些富质子核，可以用来推断可靠的信息。
Using a three-body model and realistic two-body potentials, we investigate the properties of the nuclei18Ne and28S near the proton dripline. We figure out the two-proton separation energies, occupation of the valence protons, root-mean-square radii of matter and the valence protons. Besides, the spatial correlation densities are displayed to reflect the correlation between the two valence protons. The first excited 0+state of18Ne is most likely to be a halo state according to our calculation. Turning off the Coulomb interactions among the three-body systems, we get the two-neutron separation energies and configuration of the valence neutrons of their corresponding mirror nuclei. The results indicate that the three-body model is proper to describe some proton-rich nuclei and can be used to deduce reliable information.
