The influence of plasma microfields on spectral properties of lithium-like ions in non-ideal plasma

For spectral features description of plasma containing lithium-like (or hydrogen-like) ions a model was developed which is based on steady state kinetic equations for density matrix. A solution of such equations is obtained from numerical code TRINITY. This code permits calculations of excited level populations as well as spectral gain and line profiles for emission and absorption for transitions between levels with principal quantum numbers up to 5. The model takes into consideration the influence of plasma microfields which leads to mixing of sublevels and Stark broadening of line shapes including non-linear interference effects due to coherent excitation of sublevels
