Synopsis

Since the early days of modem physics spectroscopic techniques have been employed as a powerful tool to assess existing theoretical models and to uncover novel phenomena that promote the development of new concepts. Conventionally, the system to be probed is prepared in a well-defined state. Upon a controlled perturbation one measures then the spectrum of a single particle (electron, photon, etc.) emitted from the probe. The analysis of this single particle spectrum yields a wealth of important information on the properties of the system, such as optical and magnetic behaviour. Therefore, such analysis is nowadays a standard tool to investigate and characterize a variety of materials. However, it was clear at a very early stage that real physical compounds consist of many coupled particles that may be excited simultaneously in response to an external perturbation. Yet, the simultaneous (coincident) detection of two or more excited species proved to be a serious technical obstacle, in particular for extended electronic systems such as surfaces. In recent years, however, coincidence techniques have progressed so far as to image the multi-particle excitation spectrum in an impressive detail. Correspondingly, many-body theoretical concepts have been put forward to interpret the experimental findings and to direct future experimental research. This book gives a snapshot of the present status of multi-particle coincidence studies both from a theoretical and an experimental point of view. It also includes selected topical review articles that highlight the achievements and the power of coincident techniques.

About this title

Product Description

This book is the proceedings of an International Conference on Many-Particle Spectroscopy of Atoms, Molecules, and Surfaces, held 26-29 July 2000, in Halle (Saale), Germany. 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 present status of multi-particle coincidence studies from both theoretical and experimental points of view. It also includes selected topical review articles that highlight the recent achievements and the power of coincident studies. It covers theoretical and experimental coincidence on single and double ionisation and/or excitations induced by electrons, positrons, photons, and ions. The systems under investigation range from a single atom to clusters and surfaces.
