We measured secondary-electron energy spectra of the H-like ions N[sup 6+], O[sup 7+], and Ne[sup [ital q]+]([ital q]=3,7,8,9,10) incident on a solid Pt(110) surface at different angles (10[degree]--90[degree]) using impact energies of 10[ital q] and 15[ital q] keV. Clear evidence is found for subsurface electron emission of the [ital KLL] Auger electrons. The stepwise filling of both [ital K]-shell holes of the Ne[sup 10+] projectile is observed in the electron energy spectrum. The dynamics of the filling of the [ital L] and [ital K] shells in the solid is studied for the Ne[sup 10+] ion. It is found that hollow Ne atoms are formed inside the solid. With decreasing incident charge state of the Ne projectile the [ital LMM] Auger lines are shifted to lower energies due to the different screening of the nuclear charge, which is consistent with corresponding Hartree-Fock calculations.
