Book Description
The main goal of this book is to elucidate what kind of experiment must be performed in order to determine the full set of independent parameters which can be extracted and calculated from theory, where electrons, photons, atoms, ions, molecules, or molecular ions may serve as the interacting constituents of matter. The feasibility of such perfect' and-or `complete' experiments, providing the complete quantum mechanical knowledge of the process, is associated with the enormous potential of modern research techniques, both, in experiment and theory. It is even difficult to overestimate the role of theory in setting of the complete experiment, starting with the fact that an experiment can be complete only within a certain theoretical framework, and ending with the direct prescription of what, and in what conditions should be measured to make the experiment `complete'. The language of the related theory is the language of quantum mechanical amplitudes and their relative phases. This book captures the spirit of research in the direction of the complete experiment in atomic and molecular physics, considering some of the basic quantum processes: scattering, Auger decay and photo-ionization. It includes a description of the experimental methods used to realize, step by step, the complete experiment up to the level of the amplitudes and phases. The corresponding arsenal includes, beyond determining the total cross section, the observation of angle and spin resolved quantities, photon polarization and correlation parameters, measurements applying coincidence techniques, preparing initially polarized targets, and even more sophisticated methods. The `complete' experiment is, until today, hardly to perform. Therefore, much attention is paid to the results of state-of-the-art experiments providing detailed information on the process, and their comparison to the related theoretical approaches, just to mention relativistic multi-configurational Dirac-Fock, convergent close-coupling, Breit-Pauli R-matrix, or relativistic distorted wave approaches, as well as Green's operator methods. This book has been written in honor of Herbert Walther and his major contribution to the field but even to stimulate advanced Bachelor and Master students by demonstrating that obviously nowadays atomic and molecular scattering physics yields and gives a much exciting appreciation for further advancing the field.

Book Description
Benjamin Bederson contributed to the world of physics in many areas: in atomic physics, where he achieved renown by his scattering and polarizability experiments, as the Editor-in-Chief for the American Physical Society, where he saw the introduction of electronic publishing and a remarkable growth of the APS journals, with ever increasing world-wide contributions to these highly esteemed journals, and as the originator of a number of international physics conferences in the fields of atomic and collision physics, which are continuing to this day. Bederson was also a great teacher and university administrator. The first part of this volume of Advances in Atomic, Molecular, and Optical Physics (AAMOP), entitled Benjamin Bederson: Works, Comments and Legacies, contains articles written from a personal perspective. His days at Los Alamos during World War II, working on the A bomb, are recounted by V. Fitch. H. Walther writes on the time when both were editors of AAMOP. H. Lustig, E. Merzbacher and B. Crasemann, with whom Bederson had a long-term association at the American Physical Society, contribute their experiences, one of them in the style of a poem. C.D. Rice recalls his days when he was Dean of the Faculty of Arts and Science at NYU, and the education in physics that he received from Bederson, then Dean of the Graduate School. The contribution by R. Stuewer is on Bederson as physicist historian (his latest interest). N. Lane draws some parallels between "two civic scientists, Benjamin Bederson and the other Benjamin". The papers are introduced by H.H. Stroke, in an overview of Bederson's career. A biography and bibliography are included. The second part of the volume contains scientific articles on the Casimir effects (L. Spruch), dipole polarizabilities (X. Chu, A. Dalgarno), two-electron molecular bonds revisited (G. Chen, S.A. Chin, Y. Dou, K.T. Kapale, M. Kim, A.A. Svidzinsky, K. Uretkin, H. Xiong, M.O. Scully, and resonance fluorescence of two-level atoms (H. Walther). J. Pinard and H.H. Stroke review spectroscopy with radioactive atoms. T. Miller writes on electron attachment and detachment in gases, and, with H. Gould, on recent developments in the measurement of static electric dipole polarizabilities. R. Celotta and J.A. Stroscio's most recent work on trapping and moving atoms on surfaces is contributed here. C.C. Lin and J.B. Borrard's article is on electron-impact excitation cross sections. The late Edward Pollack wrote his last paper for this volume, Atomic and Ionic Collisions. L. Vuskovic and S. Popovi ́c write on atomic interactions in a weakly ionized gas and ionizing shock waves. The last scientific article is by H. Kleinpoppen, B. Lohmann, A. Grum-Grzhimailo and U. Becker on approaches to perfect/complete scattering in atomic and molecular physics. The book ends with an essay on teaching by R.E. Collins. - Benjamin Bederson - Atomic Physicist, Civil Scientist - The Physical Review and Its Editor - Los Alamos in World War II - View from Below - Physics in Poetry - Casimir Effects - Pedagogical Notes - Atomic Physics in Collisions, Polarizabilities, Gases, Atomic Physics and Radioactive Atoms - Molecular Bond Revisited - Resonance Fluorescence in 2-Level Atoms - Trapping and Moving Atoms on Surfaces

Book Description
The rapid growth of the subject since the first edition ten years ago has made it necessary to rewrite the greater part of the book. Except for the introductory portion and the section on Mott scattering, the book has been completely revised. In Chap. 3, sections on polarization violating reflection symmetry, on resonance scattering, and on inelastic processes have been added. Chapter 4 has been rewritten, taking account of the numerous novel results obtained in exchange scattering. Chapter 5 includes the recent discoveries on photoelectron polarization produced by unpolarized radiation with unpolarized targets and on Auger-electron polarization. In Chap. 6, a further discussion of relativistic polarization phenomena has been added to the book. The immense growth of polarization studies with solids and surfaces required an extension and new presentation of Chap. 7. All but one section of Chap. 8 has been rewritten and a detailed treatment of polarization analysis has been included. Again, a nearly comprehensive treatment has been attempted. Even so, substantial selectivity among the wide range of available material has been essential in order to accomplish a compact presentation. The reference list, selected along the same lines as in the first edition, is meant to lead the reader through the literature giving a guide for finding further references. I want to express my indebtedness to a number of people whose help has been invaluable.

Book Description
Since the turn of the century, the increasing availability of photoelectron imaging experiments, along with the increasing sophistication of experimental techniques, and the availability of computational resources for analysis and numerics, has allowed for significant developments in such photoelectron metrology. Quantum Metrology with Photoelectrons, Volume 2: Applications and Advances discusses the fundamental concepts along with recent and emerging applications. Volume 2 explores the applications and development of quantum metrology schemes based on photoelectron measurements. The author begins with a brief historical background on "complete" photoionization experiments, followed by the details of state reconstruction methodologies from experimental measurements. Three specific applications of quantum metrology schemes are discussed in detail. In addition, the book provides advances, future directions, and an outlook including (ongoing) work to generalise these schemes and extend them to dynamical many-body systems. Volume 2 will be of interest to readers wishing to see the (sometimes messy) details of state reconstruction from photoelectron measurements as well as explore the future prospects for this class of metrology.

Book Description
Inverse problems are of interest and importance across many branches of physics, mathematics, engineering and medical imaging. In this text, the foundations of imaging and wavefield inversion are presented in a clear and systematic way. The necessary theory is gradually developed throughout the book, progressing from simple wave equation based models to vector wave models. By combining theory with numerous MATLAB based examples, the author promotes a complete understanding of the material and establishes a basis for real world applications. Key topics of discussion include the derivation of solutions to the inhomogeneous and homogeneous Helmholtz equations using Green function techniques; the propagation and scattering of waves in homogeneous and inhomogeneous backgrounds; and the concept of field time reversal. Bridging the gap between mathematics and physics, this multidisciplinary book will appeal to graduate students and researchers alike. Additional resources including MATLAB codes and solutions are available online at www.cambridge.org/9780521119740.

Book Description
Symposium on the Foundations of Modern Physics 1993 is the fourth in a series of conferences held in Joensuu, Finland, in the years 1985, 1987 and 1990 and is devoted to offering discussions on foundational problems of quantum mechanics and other fundamental physical theories, taking into account new experimental developments. The surveying of the progress with respect to fundamental questions of the quantum theory of measurement forms the guiding line of thought of the present Symposium, the main themes discussed being: the interrelation of quantum measurement and irreversibility; the physics of information (concerned with questions of information processing and quantum noise); quantum interference and mesoscopic quantum effects (searching for the micro-macro borderline); and the quantum-classical relationship (the need for classical pointer and their realisation).

Book Description
Light scattering has provided an important method for characterizing macro-molecules for at least three decades. Now, through the use of intense, coherent laser light and efficient spectrum analyzers and autocorrelators, experiments in the frequency and time domains can be used to study molecular motion, e.g. diffusion and flow and other dynamic processes, as well as the equilibrium properties of solutions. As a result, laser light scattering has become a powerful form of spectroscopy with applications in physics, biochemistry, and other fields. This volume, which employs a relatively simple approach in order to reach the widest audience, focuses on two main topics: classical light scattering (scattering intensity, concentration dependence, size dependence, and polydispersity) and dynamic light scattering (time and frequency dependence, translational diffusion, directed flow, rotational motion, and more). A series of useful appendixes and a list of references complete this concise, accessible work, a valuable resource for physicists, chemists, and anyone interested in the increasingly important field of laser light scattering.
