summary       We have studied the formation and decay of hollow atoms at
Au surfaces, covered by thin LiF and C60 films with thicknesses in the
monolayer range. Energy spectra of electrons arising from collisions of
hydrogenic O7+ and N6+ ions on these surfaces were measured and analyzed.
We observe that for a coverage with a C60 monolayer the electron filling
of the projectile L-shell proceeds much faster than for clean or LiF covered
Au surfaces.
