Classical Electron Radius
The classical electron radius (re), also called the Lorentz radius, is a physical constant के बराबर लगभग 2.818 × 10−15 meters. It को परिभाषित किया गया है the scale at which the electrostatic potential energy of a sphere of charge के बराबर the electron's charge equals the electron's rest mass energy. Though the electron is now understood to be a point particle, this quantity remains useful in quantum electrodynamics and atomic physics.
