Collisional-radiative model of NLTE plasma with an arbitrary radiation field
Abstract:
The collisional-radiative model for calculating the radiative and thermodynamic properties of a plasma with an arbitrary radiation field is considered. The basic equations of the model, formulas for calculating the rates of elementary processes, the absorption coefficient and emissivity, as well as the equation of state of matter are given. Methods for describing ionization potential depression in dense plasma are presented. A method is proposed for taking into account hot electrons with a temperature much higher than the plasma temperature.
