| Outline of Final Research Achievements |
In this study, we have developed an analytical method to determine both dynamic and static structure from powder diffraction profiles of simple structure materials such as diamond and pure metals. Bragg intensities, thermal diffuse scattering, and Compton scattering, etc were used for the analysis.
We successfully measured the temperature dependence of thermal diffuse scattering due to phonon for aluminum which shows relatively large amount of diffuse scattering. We also observed very small amounts of electron accumulation in charge density from Bragg intensities. We succeeded to detect weak modulation of charge density by the present developed method.
