摘要: We present analytical expressions for the dynamic structure factor, or form factor $S(k,\ensuremath{\omega}),$ which is quantity describing x-ray cross section from a dense plasma simple liquid. Our results, based on random phase approximation treatment charged particle coupling, can be applied to describe scattering either weakly coupled classical plasmas degenerate electron liquids. correctly reproduces Compton energy down-shift and known Fermi-Dirac velocity distribution $S(k,\ensuremath{\omega})$ in case of cold plasma. The usual concept parameter also reinterpreted order include effect Thomas-Fermi screening. results shown this work interpreting warm occurring inertial confinement fusion experiments modeling solid density matter found interior planets.
