After more than a century of study, the hydrogen atom still presents challenges and opportunities to theoretical as well as to experimental physicists. The discovery of the Lamb shift in the late nineteen forties, followed by the development of QED and the introduction of powerful new experimental techniques in the nineteen sixties and seventies, have preserved for hydrogen its central place in atomic physics. Part I of this book, a reprint of the work published in 1957, covers the period from the earliest days up to the late nineteen fifties. Part II, a collection of progress reports written by well-known specialists on hydrogen and hydrogen-like systems, presents the advances in theory and experiment that have occurred since that time.

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.

This is an ebook version of the "Advanced Study Guide - Chemistry - Ed 1.0" published by Step-by-Step International Pte Ltd. [ For the Higher 2 (H2) syllabus with last exam in 2016.] This ebook gives concise illustrated notes and worked examples. It is organised largely accordingly to the Singapore-Cambridge GCE A-Level Higher 2 (H2) syllabus, with additional topics to cover the equivalent syllabuses of the University of Cambridge International Examination (CIE) A Level (Core & A2), and the International Baccalaureate (IB) Higher Level (Core & AHL). The concise notes cover essential steps to understand the relevant theories. The illustrations and worked examples show essential workings to apply those theories. We believe the notes and illustrations will help readers learn to "learn" and apply the relevant knowledge. The ebook should help readers study and prepare for their exams. Relevant feedbacks from Examiner Reports, reflecting what the examiners expected, are incorporated into the notes and illustrations where possible, or appended as notes (NB) where appropriate. It is also a suitable aid for teaching and revision. Sample pages are available (in .pdf) from our website.

Atomic and molecular spectroscopy has provided basic information leading to the development of quantum mechanics and to the understanding of the building blocks of matter. It continues to provide further insight into the statics and dynamics of the microcosmos, and provides the ·means for test ing new concepts and computational methods. The results of atomic and molecular spectroscopy are of great importance in astrophysics, plasma and laser physics. The rapidly growing field of spectroscopic applications has made considerable impact on many disciplines, including medicine, envi ronmental protection, chemical processing and energy research. In particu lar, the techniques of electron and laser spectroscopy, the subjects of the 1981 Nobel prize in physics, have contributed much to the analytical poten tial of spectroscopy. This textbook on Atomic and Molecular Spectroscopy has been pre pared to provide an overview of modern spectroscopic methods. It is in tended to serve as a text for a course on the subject for final-year under graduate physics students or graduate students. It should also be useful for students of astrophysics and chemistry. The text has evolved from courses on atomic and molecular spectroscopy given by the author since 1975 at Chalmers University of Technology and at the Lund Institute of Technol ogy. References are given to important books and review articles which of different aspects of atomic and molecular allow more detailed studies spectroscopy. No attempt has been made to cover all important references, nor have priority aspects been systematically considered.

Originally published as part of the renowned Bergmann-Schaefer textbook series on experimental physics, this volume fills an important void by providing a thorough treatment of the basic: atoms, molecules, nuclei, and particles. Written by experimentalists, it forms a unique compendium of our practical knowledge of the basic elements While keeping all of the rigor necessary for a clean treatment, the authors go beyond theory and describe major experimental results that give readers a clear view of the practical side of nature.

Atomic hydrogen, the simplest of all stable atoms, has been a challenge to spectroscopists and theoreticians for many years. Here, as in similar systems like positronium, muonium and possibly helium, the accuracy of theoretical predictions is comparable to that of experimental measurements. Hence exciting confrontations are possible. This together with expected large experimental improvements explains the strong interest in the symposium held in Pisa in June-July 1988. The resulting book completely covers the precision spectroscopy of atomic hydrogen and hydrogen-like systems, and also discusses aspects of QED and the influence of strong fields.

This book illustrates the history of Atomic Physics and shows how its most recent advances allow the possibility of performing precise measurements and achieving an accurate control on the atomic state. Written in an introductory style, this book is addressed to advanced undergraduate and graduate students, as well as to more experienced researchers who need to remain up-to-date with the most recent advances. The book focuses on experimental investigations, illustrating milestone experiments and key experimental techniques, and discusses the results and the challenges of contemporary research. Emphasis is put on the investigations of precision physics: from the determination of fundamental constants of Nature to tests of General Relativity and Quantum Electrodynamics; from the realization of ultra-stable atomic clocks to the precise simulation of condensed matter theories with ultracold gases. The book discusses these topics while tracing the evolution of experimental Atomic Physics from traditional laser spectroscopy to the revolution introduced by laser cooling, which allows the manipulation of atoms at a billionth of a degree above absolute zero and reveals new frontiers of precision in atomic spectroscopy.
