The diverse of isotopes ⁷Li and ⁶Li

The diverse of isotopes ⁷Li and ⁶Li was examined on the several respects. The calculations of relativistic quantum mechanics shows that the energy levels of ⁶Li are lower than that of ⁷Li, and therefore the transitional wave length of E(1) and M(1) for ⁶Li are longer than that of ⁷Li. The variation of couple constant due to the different nuclear spin of ⁷Li and ⁶Li could be as a basis for the isotope separation between ⁷Li and ⁶Li. Ratio of the molar intensity of magnetization of ⁷Li to ⁶Li is about 13 under 100-20 K and 20000 gauss, which is favorable to separate out ⁶Li. (authors)
