Number of populated electronic configurations in a hot dense plasma

Abstract: In hot dense plasmas of intermediate or high-Z elements in the state of local thermodynamic equilibrium, the number of electronic configurations contributing to key macroscopic quantities such as the spectral opacity and equation of state, can be enormous. In this work we present systematic methods for the analysis of the number of relativistic electronic configurations in a plasma. While the combinatoric number of configurations can be huge even for mid-Z elements, the number of configurations which have non … Show more

“…The super-transition-array (STA) technique is a powerful tool to compute the radiative opacity and emissivity of intermediate to high-Z plasmas in cases where the numbers of levels and lines are so important that fine-structure and detailed-configuration-accounting methods are prohibitive. The method was implemented in several opacity codes (see for instance [1][2][3][4][5]) and successfully applied to the interpretation of absorption spectroscopy experiments, either for local-thermodynamic equilibrium (LTE) [6][7][8][9] of non-LTE plasmas [10,11]. It was also found to be of great interest for astrophysical applications [12].…”
