When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced, the electron slows down in the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E_r of a photon of radiated light. E = K - K', where K and K' are the kinetic energies of the electron before and...
