Ph. Mokler et al., EQUILIBRIUM CHARGE-STATE DISTRIBUTIONS FOR 3-16 MEV U NI IONS/, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 83(1-2), 1993, pp. 37-41
Charge state distributions for 3-16 MeV/u Ni ions penetrating C-stripp
er foils measured during UNILAC operation over the past decade are sum
marized. The results agree reasonably well with calculations including
excitation, stabilization and charge changing processes. Special emph
asis is given to the fraction of emerging few-electron ions, i.e. from
naked to Li-like ions. The results are applied to a beam foil spectro
scopy experiment investigating intra-L shell and Rydberg transitions i
n He- and Li-like Ni ions.
