Abstract
ABSTRACT In this paper, dense plasma is studied using the pseudopotential approach to account for the effect of the bound electrons on the electron‐ion potential shape near the ion core. The impact of the ion core effect on the structural and thermodynamic properties of dense plasmas is investigated taking into account both shielding effects and exchange‐correlation screening. The effects of electronic exchange and correlation are considered by using the static local field correction in the long‐wavelength limit. The ion core significantly affects the radial distribution functions and thermodynamic properties at a considered range of plasma parameters, including non‐isothermal plasma conditions. The radial distribution functions indicate strong electron clustering for a smaller minimum depth due to stronger screening, while larger steepness of the core edge shifts the peaks to shorter distances, while for the same cases the non‐ideality corrections increase.
