对准直的钡原子束（天然同位素丰度）进行了激光光谱研究。所研究线路的亚稳态地电平（3D1、2、3 和 1D2）由直接在炉孔前面的钡蒸气中燃烧的放电填充。我们可以研究 580 至 690 nm 之间的 14 条光谱线。可以确定上层和下层的张量极化率以及标量极化率的差异。高达 0.03 特斯拉的磁场中的光谱显示，与简单的 Russell-Sounders 耦合产生的模式没有偏差。
Laserspectroscopic investigations were performed on a collimated atomic beam of barium (natural isotope abundance). The metastable ground levels (3D1,2,3and1D2) of the investigated lines were populated by a discharge burning in barium vapour directly in front of the oven hole. We could investigate 14 spectral lines between 580 and 690 nm. The tensor polarizabilities of the upper and the lower level as well as the differences in the scalar polarizabilities could be determined. Spectra in magnetic fields up to 0.03 Tesla showed no deviation from the pattern resulting from a simple Russell-Sounders coupling.
