We studied the potential electron emission arising from the interaction of H-like Ne[sup 9+] ions with clean Al(110) and Pt(110) surfaces at different glancing angles (10 [degree]--90[degree]) with 90-keV impact energy. Projectile [ital KLL] Auger electrons are found to be emitted from inside the solid. Therefore, the measured electron energy distributions are influenced by solid-state effects. We present a deconvolution procedure to determine the scattering contribution to the measured spectra for Al targets. After a subtraction of the scattering contribution we compare the resulting primary emission spectra with atomic structure calculations. The calculations show that at the moment of [ital KLL] Auger electron emission the projectile [ital L] shell is completely filled for an Al target, whereas for a Pt target there were on the average only five electrons in the projectile [ital L] shell. This indicates a relatively faster [ital L]-shell filling process for Al targets.
