摘　　要：用相对论平均场理论计算了氧同位素及其镜核的基态性质,并和实验比较,发现当质子(中子)是幻数时,核的性质有规律地随中子(质子)数的变化而变化,由此间接证明了幻数核子对另一类核子无直接影响;同时,也检验了相对论平均场理论在该区域的适用性.This paper calculates the ground state properties of Oxygen＇ s isotopes and their mirror-nuclei with relativistic mean field theory. In comparasion the experiment data, it is discovered that the nucleus properties regularly change with the change of neutron （proten） numbers when the proton （neutron） number is a magic number. The results prove indirectly that the nucleus with a magic number has no direct influence over another kind of nucleus. At the same time, the applicability of relativistic mean field theory in this region is also verified in this paper.
