Doppler shift of Hαspectral lines were measured in the central cathode plasma generated by an Inertial-Electrostatic Confinement discharge in He/H2mixture. Acceleration voltages were estimated from the observed maximum shift of near wings of Hα, and agreed with potential differences between the plasma center and the cathode, estimated from the potential profiles measured by the laser-induced fluorescence method. This suggests that excited H atoms are generated by charge-exchange reactions of H ions accelerated by the potential formed inside the cathode with backgroundH atoms or molecules.

在He/ h2混合物中，测量了惯性静电约束放电产生的中心阴极等离子体中h α谱线的多普勒频移。根据观察到的Hα近翼的最大位移估计了加速电压，并与激光诱导荧光法测量的等离子体中心和阴极之间的电位差相吻合。这表明，激发H原子是由阴极内部与背景H原子或分子形成的电位加速H离子的电荷交换反应产生的。
