Diffraction of metals and alloys Interaction particles-matter

Matter is explored, particularly at the atomic scale, through the interaction between atoms (their nuclei or electronic companions) and incident radiation (X-ray photons, slow electrons, fast electrons, neutrons, infrared, ultraviolet and high-frequency radiation, etc.). In this dossier, we'll focus on electron diffraction. We'll look at the main features and make a few references to X-rays and neutrons.

In this first section, we present an approach to particle-atom interactions and introduce a few crystallographic concepts.

In the second part , we present the laws of diffraction as applied to the study of atomic structures and, in particular, those of metals and metal alloys.
