Properties of Gaseous Plasma by Mass Spectrometer and Light Spectrometer Techniques

研究了在各种气体和气体混合物中产生的等离子体中的碰撞过程。关于三体和四体离子转化过程的反应速率常数与气体温度的关系的研究仍在继续。对这种依赖关系的了解可能会导致对最近发现的四体离子转换过程的更好理解，以及对几种气体放电装置（如气体激光器）的更有效设计。研究了活性稀有气体颗粒与分子之间的能量传递过程。这些研究可能为等离子体中能量转移的机制提供更详细的信息。测量了亚稳原子的破坏频率与气体温度的关系。需要这些数据来确定哪些碰撞过程对于预测放电装置（如激光器、辉光放电开关和等离子体反应器）的行为是重要的。

Studies are conducted of collision processes occurring in plasmas produced in various gases and gas mixtures. Research continues on the dependence of the reaction rate constants of three- and four-body ion conversion processes on gas temperature. A knowledge of this dependence may lead to a better understanding of the recently discovered four-body ion conversion process and to a more efficient design of several gas discharge devices such as a gas laser. The energy transfer processes between activated rare gas particles and molecules are investigated. These studies may give more detailed information about the mechanisms of energy transfer in plasmas. Measurements are made of the dependence of the destruction frequency of metastable atoms on gas temperature. These data are needed for determining which collision processes are important for predicting the behavior of electric discharge devices such as lasers, glow discharge switches, and plasma reactors.
