摘要

<正>During the last years, many investigations were devoted to low energy highly charged ion-fullerene Cgo target collisions. The Cgo is an isolated target that can be considered as an atom-like target in collisions at large distances. It behaves as a special big 'atom' with 60-7T equivalent loosely bound electrons, which makes possible the formation of hollow atoms via multiply electron capture process W. As the impact parameter is shorter than the radius of the Ceo cage, the Ceo behaves as a tiny solid target. The energy loss of projectiles in such frontal collisions is an important parameter for understanding the energy relaxation in systems wit'h a large number of degrees of freedom.
