摘要

<正> In highly charged ions - C60 collisions, the fragmentation processes have been studied up to C9+60. For low charge state of Cq+60(g=1-4) the C2 evaporation processes have been observed. The fission processes consisting of the emission of light charged fragments have been observed typically for charge state ranging from q=3 to q=9. The multi-fragmentation processes appear from 5=4 and became quickly dominant for higher charge states. The fragmentation processes are mainly studied using a standard Time of Flight tube (TOF). With this method, only fragmentation inside the extraction region of the TOF are measured in a time window of
