Analytical results for group averaged scattering cross sections of high temperature plasmas

Multi-group method is an accepted technique for approximately solving the equation of radiative transfer. In this paper, group averaged transfer scattering cross sections, required for solving the equation of radiative transfer in a multi-group approach, are presented. Compton scattering is approximately described by the Compton cross section for free electrons at rest. In the low photon energy limit analytical results for scattering coefficients have been derived.
