Observation of plasmon excitation in liquid silicon by inelastic x-ray scattering Open
Inelastic x-ray scattering (IXS) measurements were performed for observing the excitation of bulk plasmons in metallic liquid silicon (Si). The peak due to plasmon excitation was observed within the energy loss around 17 eV. Combined with …

Asymmetrical bonding in liquid Bi disentangled by inelastic X-ray scattering Open
The structure of liquid Bi has been debated in relationship with the Peierls distortion, as crystalline Bi takes A7 structure. A recent ab initio molec- ular dynamics simulation for liquid Bi predicted a flat-topped profile of the acoustic…

Critical Indices ν and γ Experimentally Obtained at the Liquid–Vapor Critical Point in Fluid Hg Open
The critical indices ν and γ near the liquid–vapor critical point in fluid Hg were obtained by small-angle X-ray scattering measurements at high temperatures and high pressures. Although both critical indices determined by the least-square…
