抄録

The advent of third-generation synchrotron-radiation (SR) provides a new opportunity of the supreme powder diffractometry, which allows one to determine accurate charge-densities, when the collected data are analyzed by the MEM/Rietveld method. The Large Debye-Scherrer Camera with an Imaging Plate as a detector has been designed and installed at BL02B2 in SPring-8 for the charge-density study. We have succeeded in observing the significant electron-orbital hybridizations revealed in the bonding electron distributions of PbTiO 3 and BaTiO 3 , which are closely related to the ferroelectric properties.
