Electron energy loss spectra (ELS) have been obtained from polycrystalline Cr and Cr2O3 before and after surface reduction by 2keV Ar+ bombardment. The primary electron energy used in the ELS measurements was systematically varied from 100 to 1150eV in order to distinguish surface versus bulk loss p...
