Surface layers of polycrystalline silver bombarded with oxygen ions having energies from 100 to 300 eV are studied via Auger electron and X-ray photoelectron spectroscopies. Atomic and molecular oxygen together with silver in the zero-valence state are found in AgO and Ag₂O after such treatment in silver surface layers. In addition, there is positive displacement of the Ag 3d_3/2 peak by 0.5 eV, indicating an increase in spin-orbit splitting for Ag 3d_5/2–Ag 3d_3/2.
