During this interaction, the photon's direction of movement does not change. The electron's velocity along the photon's direction of movement is close to c/2 in order to allow the interaction to proceed. During the photon and electron energy exchange process, when an electron's speed is less than 0.7071c and greater than 0.5c, the photon will lose energy while the electron will gain energy; when an electron's speed is more than 0.7071c, the photon will gain energy while the electron loses energy. Three physical experiments are proposed. In the first experiment, the electron speed is set to 0.6c and a red-shift is expected to occur. In the second experiment, the electron speed is set to 0.8c and a blue-shift is expected to occur. In the third experiment, the electron speed is set to 0.7071c or 0.4c. The theory predicts that there won't be a photon wavelength change. http://pubs.sciepub.com/pmc/1/2/1/pmc-1-2-1.pdf Quantum Campton Scattering Relativity red-shift blue-shift
