Laser spectroscopy was used for the investigation of the Zeeman-hf structure of 22 lines of atomic niobium in the visible region between 573.7 and 649.4 nm. We used two methods of laser absorption spectroscopy: laser induced fluorescence (LIF) method and optogalvanic spectroscopy (OG). The source of niobium atoms was a hollow cathode discharge tube. The magnetic field of approximately 800 G was generated by a permanent neodymium magnet. We determined experimentally for the first time the Lande gJ factors for 10 levels. We also verified earlier experimental data on the hf structure as well as data from the NIST database regarding Lande gJ factors.

塞曼—原子铌超细结构的研究

激光光谱用于研究573.7nm至649.4nm之间可见区域中22条原子铌的Zeeman-hf结构。我们使用了两种激光吸收光谱方法:激光诱导荧光(LIF)方法和光电电流谱(OG)。铌原子的来源是空心阴极放电管。永磁钕磁铁产生大约800 G的磁场。我们首次通过实验确定了LandeGĴ10个级别的因素。我们还验证了有关hf结构的早期实验数据以及NIST数据库中有关Lande的数据GĴ 因素。
