A change in velocity in dynamic pulsation of an electron changes its measure of mass by the gamma factor 0.999946748 from 9.1093826 ? 10-31 Kg to 9.108897513 ? 10-31 Kg. The change in measured mass due to radial length change by a factor of 137.037 at a constant frequency f equals the Two Photon Mass pair of 2 x 2.425434789 x 10-35 Kg or 2 x 13.6 eV.
