本文研究了同位素7Li和6Li在几个方面的性质差异.用相对论量子力学计算指出,6Li的电子能级比7Li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,6Li的跃迁波长都要比7Li的长.由于7Li和6Li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,7Li的磁极化比6Li的约大13倍.7Li和6Li的磁极化这种差异,也是一种可能的同位素7Li/6Li的分离方法.
In this paper, the properties of isotopes 7Li and 6Li are studied in several aspects. According to the relativistic quantum mechanics calculations, the energy level of 6Li is lower than that of 7Li. Meanwhile, the electric dipole E (1) and magnetic dipole M ( 1), the transition wavelength of 6Li is longer than that of 7Li.Due to the different sizes of the nuclear spins of 7Li and 6Li, it can be seen that at a magnetic field of 20,000 Gauss and a temperature of 100-20 K, Magnetic polarization is about 13 times larger than that of 6Li This difference in magnetic polarization between 7Li and 6Li is also a possible isotope 7Li / 6Li separation method.
