The report describes research to determine how to numerically represent the scattering kernel for X-ray scattering from a relativistic Maxwellian distribution of electrons in a multigroup discrete Sn treatment of the equation of radiative transfer. An ordinary four term Legendre polynomial expansion of the scattering kernel was used. Ten sets of 134-group averaged Wien weighted cross section coefficients were calculated for electron temperatures between 0.5 and 20 keV, with photon energies between 0.05 and 400 keV. These studies involved the transmission of a source of X-rays through a thin slab of free electrons, varying the source and electron temperatures, the angular behavior of the source, the number of energy groups, the degree of angular quadrature, and the degree of kernel expansion.
