Research Abstract

High resolution inelastic X-ray scattering has been carried out in order to elucidate phonon dispersion relations and nature of phonon excitations in materials. We applied this technique to the investigation of interference phenomena between phonon excitation and electronic excitations such as crystal electric field (CEF) excitations originated from f-electrons in strongly correlated f-electron systems. We succeeded in the observation of the interference phenomenon between a phonon and CEF excitations inPrOs_4Sb_<12>-PrRu_4Sb_<12> system. We also investigated interference phenomena between phonon and charge fluctuation due to f-electrons.
