摘要：

We present secondary electron spectra of the H-like ions C5+ through Ne9+ interacting with conducting surfaces at variable energies down to 8 eV per charge. The detailed identification of the K and L Auger spectra and their evolution as a function of charge and energy of the ions reveals evidence for the neutralization and a significant de-excitation of atoms with giant inversion of population in front of the surface. From C to Ne a decreasing fraction of spectral features is assigned to de-excitations during reflection of the projectile at the surface.
