This graduate/research level text introduces the theory of multi-electron transitions in atomic, molecular and optical physics, emphasizing the emerging topic of dynamic electron correlation. The book begins with an overview of simple binomial probabilities, classical scattering theory, quantum scattering and correlation, followed by the theory of single electron transition probabilities. Multiple electron transition probabilities are then treated in detail. Various approaches to multiple electron transitions are covered including the independent electron approximation, useful statistical...

The book reviews our present knowledge of collision-induced absorption of infrared radiation in dense gases. The book starts with a recapitulation of essential background information. Experimental results for the absorption spectra are next discussed. Then the causes and properties of dipole moments induced by molecular interactions are reviewed. Two following chapters present the theory of collision-induced absorption in monatomic gas mixtures and in molecular gases and mixtures. The final chapter discusses related phenomena and important applications in astrophysics. The book is a practical...

This book provides a comprehensive description of the physics of Rydberg atoms, highlighting their remarkable properties by reference to their behavior in a wide range of physical situations. Following an overview of the basic properties of Rydberg atoms, their interactions with electric and magnetic fields are analyzed in detail. The collisions of Rydberg atoms with neutral and charged species are described, and the use of multichannel quantum defect theory in the study of Rydberg atomic systems is discussed.

Spectra are fundamental characteristics of atoms and ions, and are the main source of information on their structure and properties. This monograph presents a complete guide to the theory of modern spectroscopy of atoms. The book describes the contemporary state of the theory of many-electron atoms and ions, the peculiarities of their structure and spectra, the processes of their interaction with radiation, and some of the applications of atomic spectroscopy. It contains a large number of new results, which have been mainly published in Russian and are therefore almost unknown to Western...

This book describes the theory and practice of electron spectrometry using synchrotron radiation. After a short review of background theory, neon is used to elucidate the principles of the photoelectron and Auger spectra. The second part of the book looks at experimental aspects, including characteristic features of electrostatic analyzers, detectors, lenses, disturbances, and optimization, and then illustrates theory and experiment with details of recent experiments. The third part provides useful reference data, including wavefunctions, special theory, polarization and special aspects of...
