| 摘要: |
| 计算jn 组态总角动量J的允许值通常采用列举法[1]，对j ，n大的组态计算十分繁琐。本文提出计算jn组态 J 的允许值的递推方法，使计算大为简化。在 VAX-ll/730机上完成 j=1/2～15/2 分类的CPU时间，用本文方法为 3 秒，用列举法[1]为 4分50秒。列出了j=1/2～15/2分类结果，并发现文献[2]表 6 有三处差错。 |

| Abstract: |
| The enumeration method is usually used to calculate the permitted J terms of jn configuration，but it becomes too complex to be used when the values of j，n become large enough. In this paper，a recurrence method instead of the conventional one is suggsted，thus greatly simplifying the calculation. For example，using this method it takes only 3 seconds of CPU time of the VAX-11/730 Computer to finish the classification of j=1/2～15/2，Whereas about 290 seconds are needed if the enumeration method is used. The classification results of j=1/2～15/2 have been listed in a table，and it is pointed out that there are 3 errors in the table of res.[2]. |
