Book Description
The Theory of Auger Transitions reviews the Auger effect theory, relating it to the broad spectrum of atomic and physical theory. This book discusses the Auger effect involving discrete and continuous states of the atomic system, which can be used as a good testing ground for fundamental atomic theory, such as the various atomic models and their concomitant wave functions. The application of Auger spectroscopy to surface chemical analysis is also elaborated. Other topics include the symmetry and invariance, theory of the Auger process, coulomb field and coulomb wave functions, and symmetry-breaking and classification of states. The central-field calculations, many-electron atom, advances in Auger theory, and Auger electron spectroscopy and its application to surface science are likewise covered in this text. This publication is intended for scientists and atomic physicists, but is also useful to theoreticians and graduate student specializing in atomic physics.

Book Description
The physics of atomic inner shells has undergone significant advances in recent years. Fast computers and new experimental tools, notably syn chrotron-radiation sources and heavy-ion accelerators, have greatly enhan ced the scope of problems that are accessible. The level of research activity is growing substantially; added incentives are provided by the importance of inner-shell processes in such diverse areas as plasma studies, astrophysics, laser technology, biology, medicine, and materials science. The main reason for all this exciting activity in atomic inner-shell physics, to be sure, lies in the significance of the fundamental problems that are coming within grasp. The large energies of many inner-shell processes cause relativistic and quantum-electrodynamic effects to become strong. Unique opportunities exist for delicate tests of such phenomena as the screening of the electron self-energy and the limits of validity of the present form of the frequency-dependent Breit interaction, to name but two. The many-body problem, which pervades virtually all of physics, presents somewhat less intractable aspects in the atomic inner-shell regime: correlations are relatively weak so that they can be treated perturbatively, and the basic potential is simple and known! The dynamics of inner-shell processes are characterized by exceedingly short lifetimes and high transition rates that strain perturbation theory to its limits and obliterate the traditional separation of excitation and deexcitation. These factors are only now being explored, as are interference phenomena between the various channels.

Book Description
Ionization and Transition Probabilities is the first volume in Atomic Inner Shell Processes which describes the relative status of the physics of atomic inner shells. Both volumes can be applied and used in various traditional scientific disciplines. Volume I consists of 11 chapters written by different authors, each an expert in the field. The book discusses mainly the inner-shell excitation by electrons, heavy-charged particles, and photons and the atomic excitation as seen in nuclear decay. The theory of radiative and radiationless transitions is also explored in terms of single-particle descriptions and many-body approaches. Other major concepts covered in this comprehensive volume include the developments in theory of multiple decay processes; transition energies and their calculations; and energy shifts that are results of chemical environment and hyperfine interactions. This first volume serves as a valuable reference to many scientists and researchers in various fields like atomic and nuclear physics, astrophysics, chemistry, surface and materials science, and engineering or radiation shields.

Book Description
The content of this book describes in detail the results of the present measurements of the partial and total doubly differential cross sections for the multiple-ionization of rare gas atoms by electron impact. These measurements show, beside other trends, the role of Auger transitions in the production of multiply ionized atoms in the region where the incident electron energy is sufficient to produce inner shell ionization. Other processes like Coster-Kronig transitions and shake off also contribute towards increasing the charge of the ions. The incident electron having energy of 6 keV, for example, in a collision with xenon atom can remove up to nine electrons! (*) X-ray-ion coincidence spectroscopy of the electron xenon atom collisions is also described. The present measurements of doubly differential cross sections for the dissociative and non-dissociative ionization of hydrogen, sulfur dioxide and sulfur hexa fluoride molecular gases by electron impact are also described in the text of this book. The results of the measurements for sulfur dioxide molecule show how this major atmospheric pollutant can be removed from the atmosphere by electron impact dissociation of this molecule. The present results of the measurements for sulfur hexa fluoride give an insight into the dissociation properties of this molecular gas, which is being so widely used as a gaseous insulator in the electrical circuits. The book also describes the present measurements of the polarization parameters of the fluorescence radiation emitted by the electron-impact-excited atoms of sodium and potassium. In these investigations the target atoms are polarized, therefore, the measurements of the polarization parameters give information about the electron atom interaction in terms of the interference, direct and exchange interaction channels.
