Abstract
The dependence on r0 of the radiation energy of an “ultralight” electron with charge e distributed uniformly over the volume of a sphere of radius r0 in a medium without and with dispersion is considered. It is shown that in any case the value of r0 which permits agreement between theory and experimental results is several orders of magnitude greater than the classical electron radius.
