Many-Particle Spectroscopy of Atoms, Molecules, Clusters, and Surfaces

In a many-particle coincidence experiment one measures the spectrum of a few particles simultaneously emitted from a probe. The emission process is usually stimulated by an external perturbation, such as the impact of an electron, photon, or ion beam. The recorded spectrum carries important information on a variety of material properties, such as optical and magnetic characteristics. In particular, coincidence studies yield detailed information on the many-body nature of the matter. Correspondingly, many-body theoretical concepts are required to interpret the experimental findings and to direct future experimental research. This book gives a snapshot of the status of multi-particle coincidence studies from both theoretical and experimental points of view. It also includes selected topical review articles that highlight the achievements and the power of coincident studies. It covers theoretical and experimental coincidence on single and double ionization and/or excitations induced by electrons, positrons, photons, and ions. The systems under investigation range from a single atom to clusters and surfaces.
