Lohmann B. Angle and Spin Resolved Auger Emission: Theory and Applications to Atoms and Molecules

Springer, 2009. — 338 p. — (Springer Series on Atomic, Optical, and Plasma Physics 46). — ISBN: 978-3-540-74630-, 978-3-642-09407-1, 978-3-540-74629-4.The Auger effect must be interpreted as the radiationless counterpart of photoionization and is usually described within a two-step model. Angle and spin resolved Auger emission physics deals with the theoretical and numerical description, analysis and interpretation of such types of experiments on free atoms and molecules. This monograph derives the general theory applying the density matrix formalism and, in terms of irreducible tensorial sets, so called state multipoles and order parameters, for parameterizing the atomic and molecular systems, respectively. Propensity rules and non-linear dependencies between the angular distribution and spin polarization parameters are included in the discussion. The numerical approaches utilizing relativistic distorted wave (RDWA), multiconfigurational Dirac-Fock (MCDF), and Greens operator methods are described. These methods are discussed and applied to theoretical predictions, numerical results and experimental data for a variety of atomic systems, especially the rare gases, and to simple molecules.The main aim of this book is twofold. On the one hand, this book might be seen as a theoretical introduction into the broad field of angle and spin resolved electron emission processes, giving a comprehensive survey of nowadays Auger emission physics for the advanced pre- and post-graduate student. Strictly applying the methods of density matrix yields a general basis for the interpretation and analysis and leads to more advanced applications.
On the other hand, this book provides a comprehensive compendium for the active researcher on performed, current, and outlined foreseen research, related to the Auger decay, which might be useful for the planning and performing of even more exciting and sophisticated studies in a field of physics which concerns areas of not only atomic and molecular physics, but also emerging fields like chemoor biophysical applications, or even quantum information. In addition, the kind of obtained data is important for the knowledge and interpretation of different types of radiation spectra observed from NASA, ESA and the Hubble Space Telescope which will provide a database on cross sections for electron impact excitation, of highly charged ions, electron-ion recombination, photoionization, charge transfers, and X-ray emission.The book was written for graduate and post-graduate students and researchers working in this field and/or trying to get a closer insight into the theoretical description of multistep scattering processes in atomic and molecular physics. It is the first book on angle and spin-resolved Auger emission. This work will be invaluable to experienced theoreticians and experimentalists seeking to gain a deeper understanding of some properties of atoms and molecules associated with multiple electron emission.Introduction to Angle and Spin Resolved Auger Emission.
