Equation of state calculations based on the self-consistent ion-sphere and ion-correlation average atom models

We compare the predictions of two self-consistent average atom (SCAA) models. One is based on the ion-sphere (IS) and the other ion-correlation (IC) model applied to the representative plasma ion. We present shock-Hugoniot calculations for aluminum and molybdenum from zero up to high temperatures and pressures when relativistic effects are important. We also compare the form factors relevant to elastic photon scattering and we also present calculations for the emissivity and photoabsorption in hot aluminum plasma.
