Spectroscopy is a versatile tool for the characterization of materials, and photons in the visible frequency range of the electromagnetic
spectrum have been used successfully for more than a century now. But other elementary particles such as neutrons, muons and x-ray
photons have been proven to be useful probes as well and are routinely generated in modern cyclotrons and synchrotrons. They offer attractive
alternative ways of probing condensed matter in order to better understand its properties and to correlate material behavior with its structure. In particular, the combination of these different spectroscopic probes yields rich information on the material samples, thereby allowing for a systematic investigation down to atomic resolutions.

This book gives a practical account of how well they complement each other for 21st century material characterization, and provides the
basis for a detailed understanding of the scattering processes and the knowledge of the relevant microscopic interactions necessary for the
correct interpretation of the experimentally obtained spectroscopic data.
