【 摘 要 】

CH42+break up into three or more fragments in one or two-step processes were studied, our result shows that there are three reaction channels to form CH2+, H+, and H, one synchronous concerted reaction channel and two two-step reaction channels. For even more complicated fragmentation processes of CH42+dications, the fragmentation mechanism can still be identified in the present measurements.
