The long-wavelength-limit structure factor of liquid alkali metals with the classical plasma reference system

Abstract

The long-wavelength-limit structure factor of liquid alkali metals is investigated using the mean-density approximation. The one-component classical plasma model is used as the unperturbed reference system. It is shown that a consistent description of long-wavelength-limit structure factor and the overall structure factor as well as the thermodynamics can be achieved to some degree using the reduced plasma parameter.
