摘要: Abstract Charge state distributions for 3–16 MeV u Ni ions penetrating C-stripper foils measured during UNILAC operation over the past decade are summarized. The results agree reasonably well with calculations including excitation, stabilization and charge changing processes. Special emphasis is given to fraction of emerging few-electron ions, i.e. from naked Li-like ions. applied a beam foil spectroscopy experiment investigating intra-L shell Rydberg transitions in He-
