HOLLOW ION FORMATION AND DECAY IN SLOW BI46-C-60 COLLISIONS()

The interaction of slow highly charged ions with many-electron targets leads to the formation of unstable, multiply excited projectiles. We simulated the formation of such hollow ions for slow incident Bi46+ pr ojectiles and C-60 targets. Our semiclassical overbarrier simulation i ncludes resonant exchange and Auger emission of electrons. It models t he dynamical variation of level occupations and charge states during t he collision and predicts highly unstable hollow ions immediately afte r the collision. With respect to the subsequent downstream relaxation of the hollow ions, we propose a simple relaxation scheme that include s autoionizing and radiative transitions. As a consequence of this dow nstream relaxation, almost all of the resonantly captured electrons ar e emitted.
