Notes

The atomic scattering factor can be expressed by:

f = \frac{E_{a}}{E_{e}}

where $E_{a}$ is the radiation amplitude scattered by the atom and $E_{e}$ is the radiation amplitude scattered by a single electron.

Le facteur de diffusion atomique peut s'exprimer comme suit :

f = \frac{E_{a}}{E_{e}}

où $E_{a}$ est l'amplitude du rayonnement diffusé par l'atome et $E_{e}$ est l'amplitude du rayonnement diffusé par un électron isolé.
