Definition

quotient of the Planck constant and the product of the mass of the particle and the speed of light in vacuum:

λ_{C} = \frac{h}{m c_{0}}

where

$h$ :: is the Planck constant (ISO 80000-1),

$m$ :: is the rest mass (rest mass) of a particle, and

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

quotient de la constante de Planck par le produit de la masse de la particule et de la vitesse de la lumière dans le vide:

λ_{C} = \frac{h}{m c_{0}}

où

$h$ :: est la constante de Planck (ISO 80000-1);

$m$ :: est la masse au repos (rest mass) d'une particule; et

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

Notes

The wavelength of electromagnetic radiation scattered from free electrons (Compton scattering) is larger than that of the incident radiation by a maximum of $2 λ_{C}$ .

La longueur d'onde du rayonnement électromagnétique diffusé par les électrons libres (diffusion de Compton) est plus grande que celle du rayonnement incident par $2 λ_{C}$ au maximum.
