| Abstract: | The absorption spectra below the 4d threshold of cerium in Ce metal, CeF3 and CeO2 compounds were measured by using a CDM (Constant Deviation Monochromator) at the Photon Factory, KEK. The difference in structure between these spectra is discussed. The structure appeared in CeO2 were considered to be due to the tetravalent configuration of cerium (Ce4+) in the ground state. |
