Interaction Matter-Polarized Light
Résumé
This chapter presents the process of interaction of light, mainly in the xray range, with matter. The subject is introduced by some experimental evidences of x-ray absorption, emission or scattering by different kinds of material. The ways of describing the electromagnetic wave field are then briefly presented before developing its interaction with an electron in an atom. This process is then applied in the context of core x-ray spectroscopies. The absorption, the dichroism and the resonant diffraction are then specifically presented before giving some key elements to manage monoelectronic simulations.
