Abstract A detailed description of a code developed to compute the energetics and radiative properties of high temperature, low-to-moderate density plasmas is presented. Steady-state ionization and excitation populations are determined by detailed balancing arguments and rate coefficients based on the hydrogenic ion approximation. We consider contributions from bound-bound, bound-free, free-free and electron scattering processes in evaluating extinction and emission coefficients at several hundred wel... Title of program: IONMIX Catalogue Id: ABJT_v1_0 Nature of problem The thermodynamic and radiative properties of hot plasmas are often required in studying a wide variety of physical phenomena. Examples of these include hydrodynamic and radiative energy transport in astrophysical and fusion plasmas. The physical conditions of plasmas considered in this paper range from a relatively high density regime, where three-body collisions dominate all atomic processes, to a low density regime where two-body radiative processes become important. In the collisionally domi ...
