A joint experimental and theoretical study of the charge-state evolution and energy spectra of electrons ejected in forward direction in collisions of 390 MeV/u Ar17+ and 460 MeV/u Fe25+,24+,23+ ions with carbon foils of various thicknesses is presented. Due to the high charge, high projectile energies, and a wide range of thicknesses the path of sequential excitation and ionization of an initially bound electron could be followed-for ion-solid collisions-in unprecedented detail. The buildup of excited states is, through the narrowing of the Compton profile, clearly reflected in the narrowing of the convoy peak.
