Influence of the atomic description and configuration interaction effects on collisional-radiative calculations of low ionized carbon plasmas

An analysis of the influence of the atomic description and the configuration interaction effects in the calculation of plasma average ionization and relevant plasma radiative properties such as the spectrally resolved emissivities and opacities, radiative power losses and mean opacities, is performed. Since the larger effects of the configuration interaction are due to the lower ionization stages, i.e. CI and CII ions, the low temperature regime is analysed. However, a wide range of plasma densities is considered, covering this way different plasma thermodynamic regimes.
