电子的交换作用对激发态能量的影响

The effect of the electronic exchange on the energy level in excited state

根据作者提出的物理模型和简洁有效的计算方法 ,考虑电子交换效应对于单电子激发态的影响 ,计算了激发态Li原子 ( 1s2 4s) 2 S1 2 的能量 .计算结果表明 :电子的交换能对低激发态的贡献较大 ,而对较高激发态 ( 5s、6s、…以上 )在计算过程中可以忽略不计 .

In accordance with the physical model and the simple,effective calculation approach,taking into account of the electronic exchange rate which effects the sole electron in excited state,the energy of atom Li(1s 24s) 2S 1/2 excited state is given.The calculation result indicates electronic exchange energy contributes more to the lower excited states,but in the higher excited states (such as 5s,6s…etc)they can be neglected.
