X-ray core-level spectroscopy is an efficient technique to investigate the electronic state of strongly correlated systems. Recent years, experimental techniques have been rapidly developing and, especially, the progress in experimental resolution has enabled us to observe fine spectral features, which were not formerly observed. These advantages will enable us to observe spectral fine features related with the electron state related to Kondo effects and/or magnetic ordering of the Ce intermetallics.
In this study, the spectral calculation for 3d-4f resonant inelastic X-ray scattering (RIXS) of CeRh3 is shown, and the character of the final state for 3d-4f RIXS is clarified by paying attention to the incident X-ray energy and polarization. This calculation is performed with an impurity Anderson model considering full multiplet effects in addition to a realistic band effect based on a local density approximation calculation.
