Target excitation in bare ion XeAr collisions studied by electron target ion coincidences

We present electron spectra resulting from collisions of bare ions N-15(7+) and C-13(6+) on Ar and the charge state distribution of target ions resulting from C-13(6+)-Xe collisions. From both type of experiments we find evidence that electron capture accompanied by target excitation is an important reaction channel in collisions between highly charged bare ions and rare gas targets.
