Calculation and Analysis of Mean Opacity of Gold Mixtures

A screened hydrogenic model for l splitting (SHML) is used to calculate the Rosseland mean opacities of high-Z Au, Ta, Yb, Ho, Gd, Sm, Nd, Sn, Ag plasmas and mixtures of gold and these elements at high temperature (T=200-400 eV) and dense (ρ=1 g/cm3). From the calculated Rosseland mean opacities of the mixtures, Au-Nd seems to be a better choice than other mixtures. Simultaneously, the reason that the mean opacities of mixture of Au-Sn decrease slightly when T=400 eV is analyzed.
