| 摘 要： | 应用全实加关联方法计算而得到的锂原子的1s2nd (n=3–5) 态 和 1s2nf (n=4–6) 态的能量，我们可以通过量子亏损理论得到量子亏损函数，它随着能量平缓地变化。利用这些函数可以分别构造一个系统方程去求解锂原子1s2nd和 1s2nf (n=7–11)里德堡态的能量和量子亏损。我们计算了nd和nf 中心能级 (n=7–11)的间隔并和文献中已有的实验和理论数据做了比较。

| Abstract: | By using the energies of the 1s2nd(n=3—5) and 1s2nf(n=4—6) states for a lithium atom, calculated with the full core plus correlation method, quantum defect functions are obtained which vary smoothly with energy based on quantum defect theory. Then these functions are separately used to construct a system equation to calculate the energies and quantum defects of the 1s2nd and 1s2nf(n=7—11) states for the lithium atom. Separations between the centres of gravity of the nd and nf levels (n=7—11) are also predicted and compared with the experimental and theoretical data available in the literature. |
