我们报道了~ 3 He的23 P和33 D态的超精细结构的完整测定，其中观察到显著的单重态-三重态混合。这种混合是由1 s开壳层电子的超精细相互作用引起的，这种相互作用基本上与外层电子无关，因此与类单电子光谱的情况不同，超精细相互作用对高激发态的电子结构至关重要。我们的研究结果可以准确预测这些国家的结构。
We report complete determination of the hyperfine structure of 23P and 33D states of3He in which significant singlet- triplet mixing is observed. This mixing arises from the hyperfine interaction of the 1s open shell electron. The interaction is essentially independent of the outer electron; thus unlike the case of one electron-like spectra, the hyperfine interaction is crucial to the electronic structure of highly excited states. Our results allow accurate predictions of the structure of these states.
