So far, I've done nothing to actually trigger a state transition, but all of the ground work is done.
目前为止，我所做的不过是触发了一次状态转换，但是我已经做好了所有基础工作。
Cesium-133 atoms emit a thin microwave spectral line when its 55th electron jumps back from an excited state orbital to its ground state (transition).
铯133原子发射一个细的微波谱线当它的第55个电子从受激态轨道跳回基态时(跃迁)。
The agreement with experiment is fair. The ground state magnetic moments and reduced E2 transition probabilities between some low-lying states are also calculated.
基态磁矩的结果也很符合实验，我们也还计算了某些低能级之间的E2跃迁几率及分支比。
