[SIT07-15] Phonon properties of the lower mantle minerals by inelastic x-ray scattering

*Hiroshi Fukui1, Akira Yoneda2, Takashi Yoshino2, Alfred Q.R. Baron3 (1.Graduate School of Material Science, University of Hyogo, 2.Institute for Study of the Earth's Interior, Okayama Univeristy, 3.RIKEN SPring-8 Center)

Keywords:lower mantle , phonon, inelastic x-ray scattering

Inelastic x-ray scattering is a useful technique to obtain phonon properties of lower mantle minerals with single crystal samples. We would like to discuss what kind of information can be derived from IXS spectra and how to do it with treating bridgmanite and ferropericlase as examples.
