RESONANT Lα X-RAY RAMAN SCATTERING SPECTRA OF CeF3, CeO2andCeB6

Resonant Lα emission spectra of Ce compounds, CeF 3, CeO 2 and CeB 6, were measured around the LIII absorption threshold. As the energy of the incident photon is tuned at the pre-edge region and at the absorption peaks of the Ce LIII absorption spectrum, the Raman peaks are resonantly enhanced. Obtained spectra are decomposed into Raman and normal Lα emission peaks by line shape analysis. The results show that the Raman spectra provide more detailed information than the absorption spectra about the 4f configuration of Ce compounds.
