| Research Abstract |
We measured liquid dynamics at metal-nonmetal transition region and discussed the relation between the dynamic and the fluctuations derived from the transition. The experimental methods are inelastic x-ray scattering and small-angle x-ray scattering measurements ; the sample systems are liquid Se-Te mixtures, that are representative metal-nonmetal transition system and supercritical fluid water, which is as a standard system that the relation between fluctuations and liquid-gas transition is already known. These measurements revealed two common features in the transition region : density fluctuations and "fast sound" phenomena.
