This contribution will provide an overview of the possible spectroscopic techniques and experiments that become available for f-electron systems using high energy resolution X-ray emission spectrometer[1]. As an example we will show the studies of the electronic structure of cerium (Ce) and uranium (U) nanostructured materials by means of high energy resolution fluorescence detection (HERFD) and resonant inelastic X-ray scattering (RIXS) via transitions between core levels and between core and valence levels[2–5]. The experimental spectral features will be characterized using a variety of theoretical codes including the LDA+U approximation within DFT[6], atomic multiplet theory[7] and full multiple scattering FEFF[8].
