Multi-electron process in highly charged ions colliding with atoms has been an active area since 1980s. Ion-Atom collision study is important not only to understand many-body interaction dynamics, but also be demanded by application research such as controlled fusion which is based on plasma physics. Bare ions are

The cluster target system was installed to the due position last year. Several test experiments such as the test of vacuum system, the calibration of the flux and the stability of system have been done after the installation and collimation of cluster internal target. However, there are two problems which hinder us from going further. One is the blocking of nozzle which results in the failure of a long-term system running; the other is the low pumping power for Hydrogen gases in the first stage of the cluster source cham-

The cross-section ratios-ofσDE/σSC,σTE/σSC,σQE/σSC andσME/σSC as well as the relative ratios among reaction channels in double-electron active, triple-electron active and quadruple-electron active are measured in I3C6+-Ne collision in the energy region of 4. 15-11. 08 keV/u by employing position-sensitive and timeof -flight coincident techniques. The bare isotope 13C6+ ions were provided by 14. 5 GHz ECR ion source
