Intermediate-coupling calculation of atomic spectra from hot plasma

Abstract

An algorithm is presented for the detailed computation of the spectral lines in hot, partially ionized plasmas in local thermodynamic equilibrium. The procedure uses the wave functions and state probabilities determined from the average atom model for microscopic configuration accounting. We use intermediate coupling to include the detailed structure of the bound-bound transition arrays. The model is applied to bromine plasma under such temperature and density conditions that partially filled L shells occur.
