【摘要】 本文通过对快放电激励下He/Ar/F₂混合气体中ArF^*,Ar₂F^*时间分辨谱的研究,探讨了准分子ArF^*和Ar₂F^*的形成和猝灭动力学过程。分析表明,ArF^*的时间衰减过程由生成它的主要前态Ar^*的时间变化过程决定,而Ar₂F^*的时间衰减过程则取决于它自己的有效寿命。并据此测定了F₂对Ar^*的二体猝灭和Ar对Ar^*的三体猝灭系数,以及He,Ar,F₂对Ar₂F^*的二体猝灭系数和Ar₂F^*的自发辐射寿命。更多还原

【Abstract】 The formation and quenching kinetics of ArF* and Ar2F* have been studied by ive-stigating their timeresolved spectra. Analysis shows tha,t the decay process of ArF* depands on the time evolution of it’s main precursor Ar*, but that of Ar2F* is determined by its own effective lifetime. Thereby the two-body quenching rate constant of Ar* by F2, three-body quenching rate constant of Ar* by Ar, as well as two-body quenching rate constant of Ar2F* by He, Ar and F2, and the radiative lifetime of Ar2F* are determined.更多还原
