Results are presented for a theoretical model, known as the
ion model (IM), recently elaborated to calculate the radiative
opacity of a hot dense plasma. The density functional theory
is used to obtain the general set of self-consistent field
equations that describe the state of the whole ensemble of plasma
atoms and ions. Theoretical features of the
Hartree–Fock–Slater model, the detail configuration
account, and the IM are considered. The IM is used for optimal
selections of compound chemical compositions for laser and heavy
ion target designs.
