Notes

Bragg angle $ϑ$ is given by

2 d sin ϑ = n λ

where $d$ is the lattice plane spacing (lattice plane spacing), $λ$ is the wavelength (ISO 80000-7: Light) of the radiation, and $n$ is the order of reflexion which is an integer.

L'angle de Bragg $ϑ$ est donné par :

2 d sin ϑ = n λ

où $d$ est l'espacement entre plans réticulaires (lattice plane spacing), $λ$ est la longueur d'onde (ISO 80000-7: Light) du rayonnement considéré et $n$ est l'ordre de réflexion qui est un nombre entier.
