本文用时间积分谱的方法研究了快放电激励下He/Ar/Kr/F₂混合气体中Kr₂F^*的动力学,探讨了Kr₂F^*形成的通道特性,理论分析和实验结果表明,在快放电激励下,三体碰撞过程KrF^*+Kr+M→Kr₂F^*+M是形成Kr₂F^*的主要通道,而置换反应ArF^*+Kr→KrF^*+Ar又能有效地产生KrF^*。实验测量了Kr₂F^*形成的有关速率常数。 关键词：

THE KINETIC STUDIES OF KrF* AND Kr2F* IN He/Ar/Kr/F2 MIXTURES

By investigating the time integrated spectra, the kinetics of Kr₂F^* in fast discharge excited He/Ar/Kr/F₂ mixtures have been studied, the paths feature of the formation of Kr₂F^* have been probed. According to the theoretical analysis and the experimental results, it was shown that under the fast discharge excitation, the three-body collision reactions KrF^* + Kr + M→Kr₂F^* + M are the main paths to the formation of Kr₂F^* and KrF^* can be formed efficiently via displacement reaction ArF^* + Kr→KrF^* + Ar. The corresponding formation rate constants of Kr₂F^* have been measured by the experiments.
