Problem
(Compton effect)
High energy photons (γ-rays) are scattered from electrons initially at rest. Assume the photons are backscattered and their energies are much larger than the electron's rest-mass energy, E≫mec2.
(a) Calculate the wavelength shift.
(b) Show that the energy of the scattered photons is half the rest mass energy of the electron, regardless of the energy of the incident photons.
(c) Calculate the electron's recoil kinetic energy if the energy of the incident photons is 150 MeV.
