塞曼效应用于测量天体物理和实验室等离子体中的磁场。磁性白矮星大气中的磁场范围为 40 kG–1 GG。对于 >2 MG 的磁场，二次塞曼效应会导致额外的线分裂和移动。在 1 MA 脉冲发电机提供的磁场中研究了氢巴尔默线。磁场由直径为 0.8-1 毫米的杆负载产生。负载中心上的一滴CH油就是氢气的来源。低电离油层由温度为 0.5-0.6 eV 的棒的黑体发射进行背光照明。使用光栅光谱仪对α和β吸收线进行塞曼分裂。三重态中心成分的光谱位移表明氢谱线中存在二次塞曼效应。
The Zeeman effect is used for measurement of magnetic fields in astrophysical and laboratory plasmas. Magnetic fields in atmospheres of magnetic white dwarf stars are in the range 40 kG–1 GG. The quadratic Zeeman effect results in the additional split and shift of lines for magnetic fields >2 MG. Hydrogen Balmer lines were studied in magnetic fields delivered by a 1 MA pulse power generator. The magnetic field was generated by rod loads 0.8–1 mm in diameter. A droplet of CH oil on the load center was the source of hydrogen. A low ionized oil layer was backlit by blackbody emission from the rod with a temperature of 0.5–0.6 eV. Zeeman splitting of-alpha and-beta absorption lines were with a grating spectrometer. A spectral shift of the central component of the triplet indicated the quadratic Zeeman effect in hydrogen lines.
