High-energy gamma rays can reach a radiation detector by Compton scattering from the surroundings. This effect is known as back-scattering. Show that, when E>> mec2, the back-scattered photon has an energy of approximately 0.25 MeV, independent of the energy of the original photon, when the scattering angle is nearly 180?
