Nickel, in low concentration, has been implanted in carbon foil. Both the Ni 2p3/2 and the L3M45M45 Auger levels are shifted 0.9 eV relative to nickel foil, while the valence band level is shifted by 1.2 eV. The characteristic energy loss peak associated with the core and valence levels of bulk nickel is observed on the core and valence levels of implanted nickel. An analysis is presented to show that the characteristic loss peak is consistent with 3d→4s or 4s→4p shake up processes. Model-based spectra are consistent with an initial state configuration ... 3d 94s1 for implanted nickel atoms.
