| Research Abstract |
To understand the condensation process from isolated atoms to a metal, we have investigated atomic dynamics in supercritical metallic fluids at high temperatures and high pressures, such as fluid Hg and fluid A_<S2>S_<E3>, using a high-resolution inelastic x-ray scattering technique. In addition, we have obtained information on the interatomic interaction and medium-range correlation by large- and small-angle x-ray scattering measurements. From these results, it has been clarified that conduction electrons play different roles for individual and collective dynamics of atoms.
