Role of Helium Droplets in Mass Spectra of Diatomics: Suppression of Dissociative Reactions
收藏 引用
Chinese Journal of Chemical Physics 2015年 第4期28卷 -页
作者: Andrew M.Ellis Sheng-fu Yang The Nanochemistry Group Department of Chemistry University of Leicester Leicester LE1 7RH UK
It is generally accepted that electron impact of doped helium nanodroplets initially produces a positively charged helium atom, which then ionizes the dopant if the two come into contact. In effect the He+ can initiat... 详细信息
