摘要
我们利用未成对电子数与给出自旋多重度2S+1的状态数的分支图,并根据±M_L的所有状态的排列是对称出现的性质,导出一个推引等价电子组态谱项的简便方法。另外,根据矢量耦合系数的对称性质,引出一个推导二个等价电子组态谱项的更简单的规则。
By using the branching diagram on number of states of (?)iycn spin multiplicity arising from N unpaired electrons, and the bilateral sy(?)metry of all arrangements for ±M_L, a simple method for obtainig term syml(?) from a configuration of equivalent electrons is deduced. Furuhermore, on (?)metrical properties of vecior coupling coefficients, a more simple rule for (?)b'aining term symbols from a configuration of two equivalent electrons is postulated.
