四氟化碳分子电离解离过程中的异构化动力学
Isomerization dynamics in dissociative ionization of carbon tetrafluoride
摘要
Abstract
The dissociation dynamics of CF4 molecules by electron collisions with impact energy of 1.0 keV was studied by using an ion momentum imaging spectrometer.In the experiment,the three-dimensional momentum vectors of the fragment ions were measured and two isomerization channels for F2+ formation from CF42+,i.e.F2+ + CF2+ and CF+ + F2+ + F,were identified by ion time-of-flight correlation map.The kinetic energy and kinetic energy release distributions of the two channels were obtained.For the three-body dissociation channel,we analyzed the momentum correlation of the dissociated fragments using the three-body dynamics analysis schemes such as the Dalitz diagram and Newton diagram.The channel is dominated by the back-to-back emission of two charged ions,and the neutral F atom acts as a spectator which only gets a very small recoil mo-mentum.关键词
