As photon energy decreases, its cross section uniformly increases as it approaches the Thomson value and since no loop diagram is involved, it is susceptible to classical treatment and belongs to the second order graphs in Feynman diagrams.
As photon energy decreases, its cross section uniformly increases as it approaches the Thomson value and since no loop diagram is involved, it is susceptible to classical treatment and belongs to the second order graphs in Feynman diagrams. For low-energy photons perpendicular to the beam direction the differential cross section of this process obtained from the Klein-Nishina formula demonstrates almost symmetric scattering. For an electron moving at the speed of light, the scattered wavelength is the de Broglie wavelength. For 10 points, name this effect, the decrease in the energy of gamma rays or x-rays that interact with matter.
