补充资料：氦原子光谱
| 氦原子光谱 helium，atomic spectrum of 氦原子能级之间跃迁发射或吸 收的光谱。氦原子核外有2个电子，基态时处于1s1s电子组态；受激发时，通常1个电子被激发到较高能态，另1个电子仍处于1s态。氦原子中2个电子角动量遵从LS耦合，2个电子合成的总自旋S＝0和1，能级分成单层结构S＝0和3层结构S＝1两组。能级之间跃迁遵从LS耦合的选择定则，根据选择定则ΔS＝0，不同多重态之间没有跃迁，因此氦原子光谱有2个主线系，2个锐线系和2个漫线系等。单层能级之间的跃迁产生单线结构光谱，3层能级之间跃迁产生复杂多线结构光谱。人们早年对氦的两套能级尚无认识时，曾认为有两种氦，产生复杂多线结构光谱的称为正氦，产生单线结构光谱的称为仲氦；今仍沿用正氦、仲氦分别指称这两套能级和光谱。
