Abstract
Measurements of the charge fractions F(q) of 60 MeV Ni-58(18+) travers ing thin carbon foils in dependence on their thickness show a non-triv ial behavior. Particularly, the charge fraction of the analysed charge state 18+ has a minimum for foil thickness below 1.9 mu g/cm(2). This behavior can be interpreted by fast electron capture into high shells and a slow depopulation and excitation of innershells. (C) 1998 Elsev ier Science B.V. All rights reserved.
