摘要：

We present a systematic experimental and theoretical study of Li(2p <-- 2s) excitation by impact of slow (upsilon less than or equal to 1 au) singly and multiply charged ions. In particular, the scaling behaviour of excitation cross sections sigma(LiI) with projectile ion charge state q is investigated. Due to the dominance of competing electron capture channels at low impact energies E, the excitation cross sections deviate significantly from a commonly applied sigma/q = J(E/q) cross section scaling relation.
