A Massive Photon Scattering Model

A massive photon scattering model was derived that compared well with the Compton scattering experimental data concerning X-rays and gamma-ray sources. It reduces the overall quadratic deviations when compared to the Compton model. A photon mass of about 8E-32 kg/45 keV was obtained for x-rays. For the gamma-ray case, the values obtained were about 3.8E-31 kg (214 keV), 1.8E-33 (1.01), and 1.96E-31 (109.74) for 45, 90 and 135 deg., respectively. It is noted that the obtained photon mass values are extremely larger than current upper bounds based on gravitational and electromagnetic experimental (theoretical) estimates, but they are close to or above the lower bound of some dark photon models addressing the missing mass (dark matter) problem, which estimates a lower bound photon mass of about 3 keV.
