摘要：

We report studies of double-electron transfer in slow collisions (v almost-equal-to 0.2-0.4 a.u.) of the F-like (nine-electron) ions Si5+, Ar9+, Sc12+, Ti13+, Fe17+, and Cu20+ with He atoms. The transfer populates doubly excited states of the Na sequence (eleven electrons) of these elements that we study via the subsequent electron emission using high-resolution Auger spectroscopic techniques. Comparison is made to spectra that are formed by single-electron capture by Ne-like (ten-electron) ions in the 2p53s3P0,2 metastable levels. Non-Coulomb (Breit interaction) Auger decay of the Na-like metastable level 2p53s3p4D7/2 forms a prominent line in many of these spectra.
