A new approach to include electron interaction effects in super transition array opacity theory
Daniel Aberg, Brian G. Wilson, Jean-Christophe Pain
A method is presented for the improved calculation of super-shell partition functions which include the repulsive electron-electron interaction energy terms in the Boltzmann factor…

On the number of atomic configurations in hot plasmas
Jean-Christophe Pain, Daniel Aberg, Brian G. Wilson
We propose approximate and accurate formulas for the number of electron configurations in hot plasmas. Such a quantity is an ingredient of algorithms devoted to the generation of c…

On the computation of moments in the Super-Transition-Arrays model for radiative opacity calculations
Jean-Christophe Pain, Brian Wilson
In the Super-Transition-Array statistical method for the computation of radiative opacity of hot dense matter, the moments of the absorption or emission features involve partition…
