Research Abstract

The precise structure analyses for the synthesized new materials in this project were performed using the synchrotron radiation X-rays diffraction technique at SPring-8. Electron density analysis using powder and single crystals diffraction were conducted for the purpose of clarifying the electronic state of functional materials, and for the revelation mechanism of quantum physical properties from a structural viewpoint. Especially we did the starting work of the single crystal diffractometer introduced on March 2008, and established measurement technology and the analysis technique. We performed the cooperative research such as the series of clathrate compounds and Li@C_<60> fullerene in this project.
