According to my my Q;FFF theory, the mass of the electron should be also about 1/3x the mass of the neutron with equal opposite charge just about like Volkov and Tolman suggested. however, The graviton created after electron/neutron collision and electron deformation producing into a positron , its mass could could be increased about 3/4 of the mass of the original electron able to push the electron somewhat away of the neutron, . having the same, but opposite positive charge. which is supposed to be in line with with laboratorium measurements. see: https://vixra.org/author/leo_vuyk
