Abstract

<p>X-ray charge density is one of the most information rich observables in natural science. We have developed the diffractometers and measurement techniques for X-ray charge density study at one of the third generation synchrotron radiation source SPring-8. Very small amounts of aspherical electron distribution of a pure metal aluminum were observed in the static deformation density. A signal to noise ratio of high temperature powder diffraction data was improved by the data correction based on Fourier analysis.</p>
