推求j－j耦合谱项的一种新方法──因式化法

推求ｊ－ｊ耦合谱项对于研究重核原子的结构和光谱十分重要，但用人工方法推算其谱项困难很大。其难点和关键在于推算组合组态［（ｊ）ｎ］Ｊ的Ｊ值。我们采用一种新的方法“因式化法”解决了这一难题。该法利用结构化的ＴＲＵＥＢＡＳＩＣ语言编制了计算程序，并在ＰＣ－３８６ＤＸ微机上通过。利用本程序可快速、准确、清晰地推算各种等效电子组态ｊ－ｊ耦合谱项的Ｊ值。同时在程序中对计算结果进行了验证。

A NEW METHOD OF DEDUCING j-j COUPLING SPECTROS COPIC TERMS-THE FACTORIZATION METHOD

Deducing j-j coupling spectroscopic terms is very important for researching the structure and spectrum of heavy nuclear atoms. But it is very difficult to deduce the spectroscopic terms by manual calculation. The difficult point and key problem are to deduce J values of combination configurations [(j)n]J. We have solved the difficult problem by using anew method-the factorization method.We take structural TRUE BASIC language to make a calculating program for themethod and practise by PC-386DX computer. The J values of the j-j coupling spectroscopicterms of every kind of equivalent configurations can be quickly, precisely and clearly deducedby using the program and check all the calculated results in the program.
