用时间分辨朗缪尔探针技术测量了0.2Torr和0.5Torr氦氮混合气体中脉冲射频放电后放电过程中的电子能量分布函数。在技术范围内，结果表明，氮气的存在具有减缓电子平均能量衰减的作用，这一点随着混合物中氮气含量的增加而变得更加明显。这种现象可以归因于余辉中存在着长寿命的振动态或电子态，它们将能量释放到电子气中。
The electron energy distribution function in the post-discharge of a pulsed RF discharge has been measured by means of a time-resolved Langmuir probe technique, in an He-N2 mixture at 0.2 and 0.5 Torr. Within the limits of the technique, it is shown that the presence of N2 has the effect of slowing the decay of the electron average energy, this being more evident the higher is the N2 content of the mixture. This phenomenon can be ascribed to the presence of long-lived vibrational or electronic states in the afterglow which release their energy to the electron gas.
