H. KLEINPOPPEN AND J. F. WILLIAMS It has only very recently become possible to study angular correlations and coherence effects in different areas of atomic collision processes: These investigations have provided us with an analysis of experimental data in terms of scattering amplitudes and their phases, of target parameters such as orientation, alignment, and state multipoles, and also of coherence parameters (e. g. , the degree of coherence of excita tion). In this way the analysis of electron-photon, ion-photon, atom-photon, or electron-ion coincidences from electron-atom, ion-atom, or atom-atom collisional excitation has led to a breakthrough such that the above quantities represent most...
Authored by top researchers, this book discusses methodologies to quantify the properties and microstructures of aluminum, steel, and superalloys. It is a unique reference to advanced laboratory techniques in the context of characterization and property evaluation methodologies, enabling the evolution of stronger and more function-specific compositions. Topics include metallography, an atlas of microstructures, thermal analysis, x-ray diffraction, and residual stress measurement, transmission electron microscopy, electron backscattering diffraction spectroscopy, texture measurement, electron momentum spectroscopy, positron annihilation spectroscopy, and atomic probe tomography.
Here, leading scientists present an overview of the most modern experimental and theoretical methods for studying electronic correlations on surfaces, in thin films and in nanostructures. In particular, they describe in detail coincidence techniques for studying many-particle correlations while critically examining the informational content of such processes from a theoretical point viewpoint. Furthermore, the book considers the current state of incorporating many-body effects into theoretical approaches. Covered topics: -Auger-electron photoelectron coincidence experiments and theories -Correlated electron emission from atoms, fullerens, clusters, metals and wide-band gap materials -Ion coincidence spectroscopies and ion scattering theories from surfaces -GW and dynamical mean-field approaches -Many-body effects in electronic and optical response
