Definition

radius of a sphere such that the relativistic electron energy is distributed uniformly:

r_{e} = \frac{e^{2}}{4 π ε_{0} m_{e} c_{0}^{2}}

where

$e$ :: is the elementary charge (ISO 80000-1),

$ε_{0}$ :: is the electric constant (IEC 80000-6: Electromagnetism),

$m_{e}$ :: is the rest mass (rest mass) of electron, and

$c_{0}$ :: is the speed of light in vacuum (ISO 80000-1)

rayon d'une sphère telle que l'énergie relativiste de l'électron soit répartie uniformément:

r_{e} = \frac{e^{2}}{4 π ε_{0} m_{e} c_{0}^{2}}

où

$e$ :: est la charge élémentaire (ISO 80000-1);

$ε_{0}$ :: est la constante électrique (IEC 80000-6: Electromagnetism);

$m_{e}$ :: est la masse au repos (rest mass) de l'électron; et

$c_{0}$ :: est la vitesse de la lumière dans le vide (ISO 80000-1)

Notes

This quantity corresponds to the electrostatic energy $E$ of a charge distributed inside a sphere of radius $r_{e}$ as if all the rest energy (rest energy) of the electron were attributed to the energy of electromagnetic origin, using the relation $E = m_{e} c_{0}^{2}$ .

Cette grandeur correspond à l'énergie électrostatique $E$ d'une charge répartie dans une sphère de rayon $r_{e}$ comme si toute l'énergie au repos (rest energy) de l'électron était affectée à l'énergie d'origine électromagnétique, en utilisant la relation $E = m_{e} c_{0}^{2}$ .
