DETERMINATION OF THE PHOTON MASS FROM COMPTON SCATTERING. by

www.et3m.net) Considerations of Compton scattering lead to a photon mass of the order of the electron mass. It is shown that a photon mass of this order travels at c for all practical purposes, and is consistent with the photoelectric effect. It is shown that the classical relativistic theory of particle scattering violates conservation of energy at the most fundamental level, so violates conservation of energy at the quantum electrodynamical level. A new interpretation of mass is suggested in terms of the R parameter of the ECE wave equation, and the Proca equation derived directly from the tetrad postulate
