Electron Acceleration Gains Electron Mass
Whether It Radiates or Not .
For an accelerated electron, electrodynamics yields two self-forces on the electron, a radiation reaction force and a previously unappreciated retardation force. These forces are examined and compared. The traditional radiation reaction force exists only when there is radiation that produces a time rate of change of acceleration. A retardation force results whenever the electron’s self-field changes due to acceleration, and is present even if there is no radiation and the acceleration is constant. It is found that the retardation force on the electron is >>> the radiation reaction force. In a new way, this circumvents problems of pre-acceleration, and energy run-away solutions. It is predicted that because the retardation force manifests itself inertially, makes the dynamic mass of any accelerated subatomic singly charged particle about 1/137 higher than its rest mass.
