摘要：

根据k系数方法[1]，应用最弱受约束电子势模型下的简单解析波函数，系统研究了各种可能节点校正下，锂原子高里德伯态（n～40）间跃迁的振子强度与辐射寿命，得到了对应于各跃迁类的节点校正规则，在这些节点校正规则下，所得振子强度及辐射寿命与可得到的其他作者的结果非常接近，表明了k系数方法对于研究锂原子高里德伯态性质的有效性.

Abstract:

 Following the method of the coefficient K[1] and using the simple analytical wavefuntion of the Weakest Bound Electron Potential Model (WBEPM), we have studied systematically the oscillator strengths and lifetimes of the high Rydberg states (n~40) of atom Li in every case of probable adjustment of node numbers and obtained the adjusting rule for cach transition serie, the results agree with calculated oscillator strength methods by other authors. This shows the effectiveness of the coefficient k method on studying the properties of high Rydberg states of alkali atoms or alkali-like ions.
