Constants - Classical Electron Radius

Symbol: re
Value: 2.817940285(31) × 10-15 m
Category: Electron Particle Constants - Electron Particle Constants
Description: A classical distribution of charge totalling the electron's charge has electrostatic potential energy equivalent to the electron's rest mass if it were confined to a volume of this radius.
 
When determined experimentally, the value will vary greatly depending on the amount of interaction concerned.
