Calculation of opacities and emisivities for carbon plasmas under NLTE and LTE conditions

Abstract

We calculate different optical properties for carbon plasma in a wide range of temperatures and densities by using ATOM3R-OP code which has been recently developed. We have calculated average ionizations, level populations, opacities and emissivities and we focus our study on the identification with our code of Coronal Equilibrium, Non Local Thermodynamic Equilibrium and Local Thermodynamic Equilibrium regions for this kind of plasma. Moreover, we analyse the differences in the optical properties when they are calculated in Non Local Thermodynamic Equilibrium and Local Thermodynamic Equilibrium.
