SUMMARY: Angular distributions of the scattered photon in two-electron ionization of
helium by Compton scattering are studied. We show that backward scattering is 
adequately described using an uncorrelated final-state approximation, as compared
with impulse approximation (IA) results. Distributions for one- and two-electron
ejection are proportional within IA at high-photon energies.
