A Universe of Atoms, An Atom in the Universe


Book Description

jThis thoroughly updated and revised text contains a selection of well-written essays based on Silvermans work on a wide range of topics, including: quantum mechanics, including atomic and nuclear physics, electromagnetism and optics, gravity, thermodynamics, and the physics of fluids. Presenting a personal odyssey in physics, Silverman investigates processes for which no visualizable mechanism can be given, or that seem to violate fundamental physical laws (but do not). The discussions use little mathematics, and anyone with a little college physics will be able to read the book with pleasure. -Engagingly written -Easily understandable by both the general reader and the seasoned physicist -Covers a diversity of subjects from "hot" topics in contemporary physics to less widely known but subtle and intriguing issues in physics -Discusses real physical systems whose behavior provokes, surprises and challenges the imagination -This second edition is newly revised and updated




The Hydrogen Atom


Book Description

For more than a century, studies of atomic hydrogen have been a rich source of scientific discoveries. These began with the Balmer series in 1885 and the early quantum theories of the atom, and later included the development of QED and the first successful gauge field theory. Today, hydrogen and its relatives continue to provide new fundamental information, as witnessed by the contributions to this book. The printed volume contains invited reviews on the spectroscopy of hydrogen, muonium, positronium, few-electron ions and exotic atoms, together with related topics such as frequency metrology and the determination of fundamental constants. The accompanying CD contains, in addition to these reviews, a further 40 contributed papers also presented at the conference "Hydrogen Atom 2" held in summer 2000. Finally, to facilitate a historical comparison, the CD also contains the proceedings of the first "Hydrogen Atom" conference of 1988. The book includes a foreword by Norman F. Ramsey.




Atoms, Molecules and Photons


Book Description

This introduction to Atomic and Molecular Physics explains how our present model of atoms and molecules has been developed over the last two centuries both by many experimental discoveries and, from the theoretical side, by the introduction of quantum physics to the adequate description of micro-particles. It illustrates the wave model of particles by many examples and shows the limits of classical description. The interaction of electromagnetic radiation with atoms and molecules and its potential for spectroscopy is outlined in more detail and in particular lasers as modern spectroscopic tools are discussed more thoroughly. Many examples and problems with solutions are offered to encourage readers to actively engage in applying and adapting the fundamental physics presented in this textbook to specific situations. Completely revised third edition with new sections covering all actual developments, like photonics, ultrashort lasers, ultraprecise frequency combs, free electron lasers, cooling and trapping of atoms, quantum optics and quantum information.




Muonic Atoms and Molecules


Book Description

From Sunday evening, April 5, until Thursday afternoon, April 9, 1992,49 scientists from 10 countries met at the Centro Stefano Franscini on Monte VeritA overlooking Ascona, in the state of Ticino in Switzerland, for an international workshop on Muonic Atoms and Molecules. More than two-thirds of the participants presented their results in talks of 20 to 40 minutes' duration. In addition, Prof. Gabriele Torelli gave, under the patronage of the Ministro del Ambiente of the state of Ticino, Dr. Mario Camani, a lecture in Italian entitled "Un modo insolito di studiare Ie proprieta nucleari, atomiche e chimiche". The scientific program commenced on Monday morning with discussions centering on nuclear muon capture and nuclear fusion and fission, moving on to muonic atom spectroscopy in the afternoon. All of Tuesday was devoted to muon catalyzed fusion and muon transfer. On Wednesday morning, different aspects of hot muonic atoms were discussed, followed by informal gatherings in the afternoon and evening. On Thursday morning we took a look at the prospects for the TRIUMF and PSI meson factories, and new experimental methods. The conference was brought to a close in the afternoon with C.P. summarizing the events of the past days. The two organizers want to thank all participants for their contributions and for the lively discussions which often followed the different talks.

Progress in Atomic Spectroscopy


Book Description

W. HANLE and H. KLEINPOPPEN In 1919, in the first edition of Atombau and Spektrallinien, Sommerfeld referred to the immense amount of information which had been accumu lated during the first period of 60 years of spectroscopic practice. Sommer feld emphasized that the names of Planck and Bohr would be connected forever with the efforts that had been made to understand the physics and the theory of spectral lines. Another period of almost 60 years has elapsed since the first edition of Sommerfeld's famous monograph. As the editors of this monograph, Progress in Atomic Spectroscopy, we feel that the present period is best characterized by the large variety of new spec troscopic methods that have been invented in the last decades. Spectroscopy has always been involved in the field of research on atomic structure and the interaction of light and atoms. The development of new spectroscopic methods (i.e., new as compared to the traditional optical methods) has led to many outstanding achievements, which, together with the increase of activity over the last decades, appear as a kind of renaissance of atomic spectroscopy.




Atomic Physics 4


Book Description

ATOMIC PHYSICS 4 extends the series of books containing the invited papers presented at each "International Conference on Atomic Physics." FICAP, the fourth conference of this type since its foun dation in 1968, was held at the University of Heidelberg. The goal of these conferences, to cover the field of atomic physics with all its different branches, to review the present status of research, to revive the fundamental basis of atomic physics and to emphasize future developments of this field as well as its applications was met by more than thirty invited speakers, leaders in the field of atomic physics. Their talks were supplemented by more than two hundred contributed papers contained in the FICAP Book of Abstracts. This volume begins with papers given in honour and memory of E. U. Condon, to whom this conference was dedicated. It continues with articles on fundamental interactions in atoms and Quantum electrodynamics, on the fast progressing field of high energy heavy ion collisions and Quasi-molecules, on electronic and atomic collisions and the structure of electronic and ~-mesic atoms. The volume closes with contributions concerning the application of la sers in atomic physics, a new field of vastly increasing importance to fundamental experiments as well as applications. We feel that this book contains a very stimulating account of the present main streams of research in atomic physics and its possible future di rections.
