多电子原子和离子的等电子系参数的研究(Ⅱ)——跃迁概率与振子强度的计算

应用我们提出的k系数校正方法,使用最弱受约束电子势模型下的简单解析波函数,则等电子系各成员的跃迁结果只随核电荷数Z变化。由此,非常方便地进行了LiI跃迁概率和3电子系振子强度的计算,与量子亏损方法相比,不但能够反映出等电子系跃迁的规律性,而且结果具有相当好的精度。表明结合k系数校正的最弱受约束电子势模型方法,有利于等电子系规律的研究。关键词：

A STUDY ON PARAMETERS OF THE ISOELECTRONIC SEQUENCE OF MANY-ELECTRON ATOMS AND IONS ( Ⅱ )——CALCULATIONS OF THE TRANSITION PROBABILITIES AND OSCILLATOR STRENGTHS

Following the method of the adjusting coefficient k we introduced and using the simple analytical wavefunction within the weakest bound electron potential model (WBEPM), the transition results of each member in the isoelectronic series only vary with its nucleus charge number Z. So we can conveniently calculate the transition probabilities of Li I and the oscil-lator strengths of the 3-electron series. The comparisons with other methods show that not only the regularity of transitions in the isoelectronic series is reflected, but also a more accu-rate result could be obtained. The WBEPM theory with adjusting coefficient k can provide good trial wavefunctions for detailed atomic calculations, particularly for the study of isoelectronic series.
