    "abstract": "An insight into bispinor analysis makes it possible to describe the electron\nin selfaction as a fundamental steady state. The electromagnetic theory, and\nthe Dirac equation for the study of an electron in presence of external\npotentials, follow as natural extensions of the equations that rule the\nelectron in selfaction. The electromagnetic coupling constant ($\\alpha$) and\nthe coupling constant ($\\beta$) of a gauge invariant matrix vector potential\nare interrelated by the equation that defines the electron structure. Here, two\nbispinor components carry 1/3 and 2/3 of the physical properties of the\nelectron: electric charge, mass, spin and magnetic moment. These fractions of\nthe electron charge seem to be a feature common to both leptons and hadrons. An\neigenvalue equation involving the invariants of the selfpotentials ultimately\ndetermines $\\alpha$ and $\\beta$.",
