摘要：

We have performed measurements on charge-state distributions of target ions produced in collisions of C6+, N6+, O6+, Ne6+, Ar6+ and Kr6+ on Ar. Charge states of Ar target ions higher than the initial projectile charge state are observed for C6+, N6+ and O6+. This intriguing observation seems to imply that even in low-energy collisions (similar to keV amu(-1)) of highly charged ions on gas targets excitation of the target occurs due to inner-shell electron capture. For collisions of Ar6+ and Kr6+ on Ar less than six electrons are transferred.
