A 200 keV electron strikes a copper target and is brought to rest producing a single X-ray photon. The photon then enters a carbon target and is scattered by a free electron. What is the Compton scattering angle relative to the direction of the incident X-ray if the energy of the scattered X-ray is 0.11MeV?
