Hartree-Fock statistical approach to atoms and photoabsorption in plasmas

Abstract: Hartree-Fock equations for plasma atoms are proposed and used in the superconfiguration method of photoabsorption calculation. They involve statistical sums, taking into account integer shell occupation numbers and finite temperature effects. These sums are evaluated using electron and hole counting. Their use is also shown to be relevant to the treatment of orbital relaxation in the final states of optical transitions. ͓S1063-651X͑97͒50805-1͔ PACS number͑s͒: 52.25.

“…As seen in Fig. 2, the 2p − 4d opacity does not include anymore the photoionization process 2p 6 [3] N−12 → 2p 6 [3] N−13 , which explains the absence of the background of ∼ 10 2 cm 2 /g. But the combined opacity (green broken curve, addition of 2p − 3d and screened 2p − 4d) is now in very good agreement with the full consistent computation.…”

“…The recent experiment performed on the LULI2000 facility [4] aimed at checking a similar effect at fixed T but varying the atomic number Z: at T ∼ 20 eV, the 2p − 3d splitting is expected to vanish when Z decreases from 29 (Cu) to 26 (Fe). To describe this experiment, several models have been used and compared [5]: a statistical analysis with the superconfiguration code SCO [6], detailed-level accounting approaches using either HULLAC [7] or FAC [8] packages, the mixed approach SCO-RCG [9] combining the SCO approach with a detailed line analysis based on Cowan's code, and the collisional-radiative code SCRIC [10] suited to characterize the non-local-thermodynamic-equilibrium effects. It turned out that HULLAC a e-mail: michel.poirier@cea.fr This is an Open Access article distributed under the terms of the Creative Commons Attribution License 2.0, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.…”

“…A few years ago, Blenski et al [2,3] generalized the statistical HartreeFock approach to atoms in plasmas at finite temperature in the framework of the super-configuration approximation successfully applied in the STA (Super Transition Array) method [4]. In the following, such a theory will be refered to as "canonical statistical HF theory".…”
