Download or read book Direct Measurement of the Hyperfine Structure Interval of Positronium Using High Power Millimeter Wave Technology written by Akira Miyazaki and published by Springer. This book was released on 2015-06-01 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the author develops new high-power millimeter wave techniques for measuring the hyperfine structure of positronium (Ps-HFS) directly for the first time in the world. Indirect measurement of Ps-HFS in the literature might have systematic uncertainties related to the use of a static magnetic field. Development of the millimeter wave devices supports the precise determination of Ps-HFS by directly measuring the Breit-Wigner resonant transition from o-Ps to p-Ps without the magnetic field. At the same time, the width of the measured Breit-Wigner resonance directly provides the lifetime of p-Ps. This measurement is the first precise spectroscopic experiment involving the magnetic dipole transition and high-power millimeter waves. The development of a gyrotron and a Fabry-Pérot cavity is described as providing an effective power of over 20 kW, which is required to cause the direct transition from o-Ps to p-Ps. Those values measured by the newly developed millimeter wave device pave the way for examining the discrepancy observed between conventional indirect experiments on Ps-HFS and the theoretical predictions of Quantum Electrodynamics.

Download or read book Basics of Interferometry written by P. Hariharan and published by Academic Press. This book was released on 2012-12-02 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for those who have some knowledge of optics, but little or no previous experience in interferometry. Accordingly, the carefully designed presentation helps readers easily find and assimilate the interferometric techniques they need for precision measurements. Mathematics is held to a minimum, and the topics covered are also summarized in capsule overviews at the beginning and end of each chapter. Each chapter also contains a set of worked problems that give a feel for numbers. The first five chapters present a clear tutorial review of fundamentals. Chapters six and seven discuss the types of lasers and photodetectors used in interferometry. The next eight chapters describe key applications of interferometry: measurements of length, optical testing, studies of refractive index fields, interference microscopy, holographic and speckle interferometry, interferometric sensors, interference spectroscopy, and Fourier-transform spectroscopy. The final chapter offers suggestions on choosing and setting up an interferometer.

Available in PDF, EPUB and Kindle. Book excerpt: This is the only handbook available on X-ray data. In a concise and informative manner, the most important data connected with the emission of characteristic X-ray lines are tabulated for all elements up to Z = 95 (Americium). The tabulated data are characterized and, in most cases, evaluated. Furthermore, all important processes and phenomena connected with the production, emission and detection of characteristic X-rays are discussed.

Download or read book The Anomalous Magnetic Moment of the Muon written by Fred Jegerlehner and published by Springer Science & Business Media. This book was released on 2008 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the present state of knowledge of the anomalous magnetic moment a=(g-2)/2 of the muon. The muon anomalous magnetic moment is one of the most precisely measured quantities in elementary particle physics and provides one of the most stringent tests of relativistic quantum field theory as a fundamental theoretical framework. It allows for an extremely precise check of the standard model of elementary particles and of its limitations.

Available in PDF, EPUB and Kindle. Book excerpt: After the development of the tunable laser, experimental studies in Rydberg states of atoms and molecules grew at a remarkable rate. Fundamental questions were resolved, opening doors for more experimental activity and theoretical inquiry. In this comprehensive summary of knowledge of Rydberg states, which was originally published in 1983, Professors Stebbings and Dunning brought together a select collection of experimental and theoretical discussions. Composed of works by the acknowledged leaders in the field, this volume will be of value for anyone with an interest in molecular physics.

Download or read book Antihydrogen and Fundamental Physics written by Michael Charlton and published by Springer Nature. This book was released on 2020-07-19 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of high-precision antihydrogen spectroscopy has opened up the possibility of direct tests with unprecedented accuracy of some of the most fundamental principles of physics, notably Lorentz and CPT symmetry and the Einstein equivalence principle. This book reviews these principles, emphasising their interconnections in quantum field theory and general relativity and the special role of antimatter, and explores how they may be tested in current and forthcoming experiments on antihydrogen. Original research results relevant to the experimental programme of the ALPHA collaboration at CERN are presented, together with the implications for antihydrogen of proposed theories featuring novel `fifth-force' interactions.
Download or read book Spectrum Of Atomic Hydrogen The Advances written by G Series and published by World Scientific. This book was released on 1988-06-01 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
