在脉冲和连续射频辉光放电（GD）等离子体中，对OI 844.6 nm和Ar I 842.5 nm谱线的相干前向散射（CFS）和原子吸收（AA）进行了比较。塞曼分裂的常规AA光谱和CFS辐射的自吸收剖面可以观察到不同的磁场，以上~50和~10 mT，分别。GD管的磁场的轴向变化的计算和由测量的塞曼分裂确定的磁场允许我们确定的位置的最高和第二高的激发氩原子的数密度的相对最大值在较低的状态的Ar I 842.5-nm的过渡。
Comparison of the coherent forward scattering (CFS) and atomic absorption (AA) of the O I 844.6- nm and Ar I 842.5 -nm lines was performed in pulsed and continuous radio-frequency glow discharge (GD) plasma. Zeeman splitting of the conventional AA spectra and the self-absorption profile of CFS radiation could be observed for different magnetic fields, above ~50 and ~10 mT, respectively. The calculation of the axial variation of the magnetic field of the GD tube and the magnetic field determined by the measured Zeeman splitting allowed us to determine the locations of the highest and the second highest relative maximum of the number density of excited argon atoms in the lower state of the Ar I 842.5-nm transition.
