Abstract

A plasma equation of state in a gas domain is derived from Saha model accounting for ion cores. Calculations for Cu are performed using the stiff ion core model for densities of up to 10⁶ g/cm³. A compressible ion core model is also developed. The Tomas–Fermi model is applied to condensed plasma. Both models are unified into a thermodynamically consistent equation of state.
