The following is a paper by H. Aspden published in Lettere al Nuovo Cimento, v. 33, pp. 213-216 (1982).
Abstract: This paper correlates data from g-factor measurements and energy radiation theory, both indicating that the electron has a characteristic radius from which radiation is reflected of 1.1547 times the classical radius e2/mc2. More important, the paper resolves an existing anomaly by reconciling the energy radiation property of the accelerated electron and the non-radiation hypothesis required to account for inertia according to the law E = Mc2.
