| Keywords | Synchrotron Radiation, X-ray Diffraction, Crystal Structure Analysis, Charge Density Analysis, Solid State Physics, Fullerene |
| Current Research Topics | We discuss physical properties of crystals from the atomic structure and charge density distribution determined by high resolution x-ray diffraction using synchrotron radiation from SPring-8. The recent research subjects are (1) Development of methods for accurate x-ray structure analysis using synchrotron radiation (2) Structure determination of endohedral metallofullerenes by single crystal charge density analysis |
