Comparison of Collisional and Raidative Plasma Kinetics Model (CRM) and Average Ion Model (AIM) in Dense Plasma

Estimation of accuracy of SIM approximation for model systems (Bohr’s and Slator’s CRMs) has shown that in a number of cases SAIM, regarded as an approximation of “exact” CRM, can satisfactorily (with precision up to two times) represent the effect of “dynamic” correlations upon plasma radiation spectrum in conditions of strong non-LTE, including consideration of Auger processes in a wide range of densities, temperatures and compositions of multicharge plasma.
