Abstract

The expressions for the energy matrix elements and for the radiative transitions in the jj coupling can be obtained from the respective LS expressions by making a few simple changes. The results shown as examples are compared with other treatments, where the two formulations are deduced in parallel, without making use of these simple rules. We emphasize that the rules were found by heuristic reasoning. In all cases the application of the rules are in accordance with published results. This work completes two previous papers published in this journal (References 19 and 20).

原子和核光谱学中从LS到jj表达式的一个启发式程序

通过一些简单的改变，可以从各自的LS表达式中得到jj耦合中能量矩阵元素和辐射跃迁的表达式。作为例子的结果与其他处理进行了比较，在这些处理中，两个公式并行推导，而不使用这些简单的规则。我们强调这些规则是通过启发式推理发现的。在所有情况下，规则的应用都要与公布的结果一致。这项工作完成了之前在该杂志上发表的两篇论文(参考文献19和20)。

期刊介绍： The Revista Mexicana de Física (Rev. Mex. Fis.) publishes original papers of interest to our readers from the physical science com unity. Language may be English or Spanish, however, given the nature of our readers, English is recommended. Articles are classified as follows: Research. Articles reporting original results in physical science. Instrumentation. Articles reporting original contributions on design and construction of scientific instruments. They should present new instruments and techniques oriented to physical science problems solutions. They must also report measurements performed with the described instrument. Reviews. Critical surveys of specific physical science topics in which recent published information is analyzed and discussed. They should be accessible to physics graduate students and non specialists, and provide valuable bibliography to the specialist. Comments. Short papers (four pages maximum) that assess critically papers by others authors previously published in the Revista Mexicana de Física. A comment should state clearly to which paper it refers.
