Multigroup radiation cross sections of high temperature uranium plasmas

Multigroup cross sections for thermal radiation in a uranium plasma at solid state density and temperatures in the KeV range are presented. Bound-free and free-free absorption is taken into account. Compton scattering is approximately described by the Thomson formula and by the Compton cross section for free electrons at rest. The results contain tables of one-group Rosseland means of the mean free path (valid in the optically thick limit) and of six-group Planck absorption and scattering cross sections (valid in the optically thin limit).
