The X-ray Emission of Cerium Oxide

Abstract Using a combination of spectral simulation with FEFF and experimental data for metallic Ce, it has been possible to extract the Cerium Oxide-only M4,5 X-ray Emission Spectrum (XES) from an experimental result, which had been produced utilizing a combined CeOxide/Ce sample. It is shown that the XES emission for CeOxide-only is significantly different for the M4 and M5 edges, with the M4 XES consistent with normal XES and the M5 XES exhibiting a continued enhancement associated with a threshold effect, connected to Resonant Inverse Photoelectron Spectroscopy (RIPES).
