Measurements have been made of projectile K-Auger electron emission during interactions of 60-keV N[sup 6+] ions grazingly incident on a Au(011) single crystal whose work function was modified by sub-monolayer deposits of Cs. K-Auger spectra were obtained for 5[degree], 1.4[degree], 0.7[degree], and 0.3[degree] incidence angles, and for clean, as well as cesiated, Au surfaces characterized by a reduction in work function of as much as 3 eV. For the incidence angles smaller than 5[degree], an enhancement of the above-surface K-Auger component could be discerned with decreasing surface work function. This enhancement was qualitatively reproduced by an above-surface neutralization simulation based on the classical over-the-barrier model which was modified to treat the case of a two-component'' surface.
