We report results of an experimental and theoretical study of complex UV line shapes of Ne II 369.421 nm, Ne II 371.308 nm and Ne II 372.711 nm lines in the cathode sheath (CS) region of an abnormal glow discharge in pure neon. The experimental profiles were studied by means of the optical emission spectroscopy (OES) in conjunction with an iterative CS kinetic model. It is shown that our theoretical model describes the experimental line shapes and that, with the aid of the measured Stark shifts of atomic neon lines, it can be used for the determination of the most important CS parameters (e.g. the thickness of the CS region, distribution of electric field, and the gas temperature). We draw attention to the possibility of determining the electric field strength in CS from the width of the pedestal of the complex line profiles.

异常辉光放电的阴极鞘中复杂的UV Ne II线形

我们报告了在纯氖中异常辉光放电的阴极鞘（CS）区域中，Ne II 369.421 nm，Ne II 371.308 nm和Ne II 372.711 nm线的复杂UV线形状的实验和理论研究的结果。实验轮廓通过光学发射光谱法（OES）结合迭代CS动力学模型进行研究。结果表明，我们的理论模型描述了实验线的形状，并且借助原子氖线的测得的Stark位移，它可以用于确定最重要的CS参数（例如CS区域的厚度，电场分布和气体温度）。我们提请注意从复杂线轮廓的基座宽度确定CS中电场强度的可能性。
