X-Ray Diffraction by Crystalline Materialsar with the mathematical formalism of scattering and diffraction. The physical principles of diffraction by crystals are then introduced, and finally the phase problem in crystallography is presented and the main methods to solve it are shortly outlined. Few notes on the refinement process and on powder diffraction are also reported.

Quantum Description of the Matter-Radiation Interactionstates of the electron systems can be studied in a single-particle picture or in a many-electron scheme; the two approaches will be compared in the study of the elementary processes of interaction with light at different levels of approximation for the initial, final and intermediate states of the matter system.

A Close Look into the Low Energy Region of the XAS Spectra: The XANES Region progresses in theory and computation have extended the application of XANES spectroscopy in many different fields. This chapter aims to be a guide across the different approaches to XANES data analysis, from the phenomenological semi-quantitative methods, to accurate ab-initio modelling and data fitting.

Photoemission Spectroscopy: Fundamental Aspectsers who need to be introduced to this field is ever increasing, and the spectrum of backgrounds that they possess is very large. Aim of this chapter is to provide for all of them a basic introduction to the models upon which photoemission is based and, by the help of simple examples, to explain what information photoemission can provide.

The High-Frequency Atomic Dynamics of Disordered Systems Studied by High-Resolution Inelastic X-Ray spectra and to extract parameters of interest for the investigation of disordered systems. With the help of some selected examples, the present status of the field is discussed, with particular reference to the vibrational dynamics in glasses, and to the high-frequency relaxations in liquids.

Introduction to Synchrotron Radiationadiation; today electron storage rings are routinely used to provide synchrotron radiation to users in a wide spectral range from infrared to hard X-rays. Thanks to its peculiar characteristics, synchrotron radiation is one of the more powerful tools for investigating the properties of matter in man
