摘要
对激光产生的原子簇离子,通过质量选择,可以对选出的原子簇离子进行碰撞诱导解离或光解离研究,在对实验记录的解离质谱的分析中发现,同一系列碎片离子的相对丰度分布符合一定的统计规律.不同的统计分布形式对于不同的解离机理,通过求解解离反应的动力学方程,得到碎片高子统计分布的函数表达式,从而可以通过分析解离质谱中碎片离子的统计分布,探讨相应的原子簇离子解离反应的机理.
Dissociation studies of mass-selected cluster ions have been carried out ona home-made apparatus. From analysis of the recorded dissociation mass spectra, it wasfound that fragmant distribution of dissociated cluster ions follows a statistical distribu-tion model. In this paper, kinetic equations of two dissociation pathways are discussedand their analytical solutions are presented. Based on the distribution functions, recordeddissociation mass spectra of cluster ions are analyzed and attributed to the different frag-mantation channels.
