中文摘要：

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.

英文摘要：

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.
