CONT

Diffraction des poudres. En diffraction des échantillons polycristallins, on irradie une fine poudre par un faisceau monochromatique, par exemple le rayonnement d'un tube à anode de cuivre. On observe de cette manière, à des angles déterminés, nommés angles de diffraction, les faisceaux diffractés par les plans cristallins. La relation entre l'angle de diffraction et la distance interatomique du réseau cristallin est donnée par la loi de Bragg [...]
