基于 Langevin (1905) 和 Hasse (1926) 理论的扩展，开发了一种具有电荷交换的离子中性物质碰撞模型，用于辉光放电的粒子模拟。通过He+-He、Ne+-Ne、Ar+-Ar和Kr+-Kr碰撞漂移速度的蒙特卡罗计算验证了模型的有效性。结果显示与实验数据和矩量法解具有良好的一致性，特别是对于重气体。通过适当选择模型中无量纲碰撞参数的截止值，适用于能量为1 keV的离子碰撞。
An ion-neutral species collision model with charge exchange is developed for use in particle simulation of a glow discharge based on an extension of the theory of Langevin (1905) and Hasse (1926). The validity of the model is checked by Monte Carlo calculation of drift velocity for He+-He, Ne+-Ne, Ar+-Ar and Kr+-Kr collisions. The results show good agreement with the experimental data and the solution by the moment method, especially for heavy gases. By proper choice of the cut-off value of the dimensionless impact parameter in the model, it is applicable to a collision of ions of energy 1 keV.
