Abstract

Using the detailed configuration accounting with the term structures treated by the unresolved transition array model, we have presented a method to calculate the spectral-resolved opacity for high temperature and density plasmas. Due to the fully relativistic treatment, incorporated with the quantum defect theory to handle the huge number of transition arrays from configurations with high principal quantum number, we can calculate the opacity of any medium- and high-Z plasmas conveniently. In the present work, the frequency-dependent opacity and the Rosseland mean opacity are calculated for a mixture of gold and gadolinium at a high temperature, 250 eV, and three densities, 0.1 g/cm(3), 1.0 g/cm(3), and 10.0 g/cm(3). Agreement between ourtheoretical results and experimental measurements and other theoretical simulations is obtained.
