| 摘 要： | 在引入了BCS理论的相对论平均场模型框架内，通过系统研究氧同位素偶偶核的单粒子能级间隔、单粒子能级占有概率比、对作用效应和粒子数涨落，比较了14O,22O和24O三个核的中子闭壳效应，最后从理论上预言丰质子核14O有着比丰中子核22O和24O更强的中子闭壳效应.

| Abstract: | By systematically analyzing the single particle level, the single particle occupation probability near the Fermi surface, paring energy effect and the rule of nuclear particle number fluctuation of even-even nuclei of oxygen isotopes within the relativistic mean-field model with BCS theory, we compare the neutron closed shell effect of 14O,22O and 24O nuclei, and finally predict theoretically that the proton-rich 14O nucleus has stronger neutron closed shell effect than 22O and 24O nuclei. |
