本文研究了同位素7 Li和6 Li在几个方面的性质差异．用相对论量子力学计算指出，6 Li的电子能级比7 Li的能级低，同时，对电偶极E （1）和磁偶极M （1）的能级跃迁波长，6 Li的跃迁波长都要比7 Li的长．由于7 Li和6 Li的核自旋的大小不同，可以看出在磁场2万高斯和温度100－20 K之间，7 Li的磁极化比6 Li的约大13倍．7 Li和6 Li的磁极化这种差异，也是一种可能的同位素7 Li／6 Li的分离方法．

The diverse of isotopes 7 Li and 6 Li was examined on the several respects.The calculations of relativistic quantum mechanics shows that the energy levels of 6 Li are lower than that of 7 Li, and therefore the transitional wave length of E(1) and M(1) for 6 Li are longer than that of 7 Li.The variation of couple constant due to the different nu-clear spin of 7 Li and 6 Li could be as a basis for the isotope separation between 7 Li and 6 Li.Ratio of the molar intensi-ty of magnetization of 7 Li to 6 Li is about 13 under 100-20 K and 20, 000 gauss, which is favorable to separate out 6 Li.
