用碱金属原子的模型势结合B-样条函数展开方法研究了静电场中铷原子里德堡态的能级结构特点,计算了铷原子主量子数n由16到25之间的(n+3)s和(n,k)态间的Stark能级反交叉位置和宽度,得到了与实验相一致的结果,并给出了计算铷原子在静电场中高里德堡态能级反交叉位置的经验公式.
With a potential model of alkali-metal atoms and B-spline expansion technique, the structure of the energy levels for Rydberg states of Rubidium is investigated. We calculated the positions and widths of anticrossing between ( n + 3) s and ( n, k ) Stark states with principal quantum number n between 16 and 25. Our results are in agreement with the experimental data. And we obtained two empirical formulas which can be used to estimate the positions of anticrossing for high Rydberg states of Rubidium in static electric field.
