Abstract: 

We present secondary electron energy spectra of Ne^q+ (q=3,7,8,9,10), incident on a solid Pt(110) surface at different angles (10°–90°) with impact energies of 10 q keV. In the case of Ne¹⁰⁺ projectiles the filling of both K shell holes can be distringuished in the electron energy spectrum. It was found that the L shell is populated with 5 electrons during the first KLL Auger process (K²LL) and that the L shell is almost filled during the second one (K¹LL). The index denotes the number of vacancies in the K shell. The ^IK¹L′L/^IK²L′L intensity ratio varies as a function of the incidence angle and of the observation angle. Therefore, clear evidence is found for sub‐surface KLL Auger electron emission. Furthermore, a variation of the incident charge state of the Ne projectile from 10 to 7 results in a shift of the LMM Auger maxima to lower energies, which is consistent with corresponding Hartree‐Fock calculations.
