Abstract
We discuss hollow atom formation and stabilization of electrons on following collisions at The experimental information consists of the final projectile charge-state distributions i.e., the relative distributions of the number of stabilized electrons, s, and the corresponding mean values as functions of q. We use the classical over-the-barrier model to deduce sequences of effective principal quantum numbers and find that the hollow atom formation is completed above the surface of the cage for all q. For (filled L shells), the last electrons are transferred from delocalized outer orbitals directly to the projectile M shell (side-feeding), while several intermediate shells are left open for larger q leading to further electron transfer at intermediate distances and simultaneous electron emission from higher projectile shells. At still closer distances, localized carbon K-shell electrons are transferred directly to the argon L and 11) and M shells The direct transfer to the L shell of and is manifested as significant enhancements of for and
