Download or read book Stark Effect In A Hydrogenic Atom Or Ion Treated By The Phase integral Method With Adjoined Papers By A Hokback And P O Froman written by Nanny Froman and published by World Scientific. This book was released on 2008-03-14 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats the Stark effect of a hydrogenic atom or ion in a homogeneous electric field. It begins with a thorough review of previous work in this field since 1926. After the Schrödinger equation has been separated with respect to time dependence, centre of mass motion and internal motion, followed by a discussion of its eigenfunctions, the exact development in time of the probability amplitude for a decaying state is obtained by means of a formula analogous to the Fock-Krylov theorem. From this formula one obtains by means of the phase-integral approximation generated from a particular base function non-relativistic formulas for profiles, energies and half-widths of the Stark levels. These formulas are then transformed into formulas expressed in terms of complete elliptic integrals. The formulas thus obtained are used for the calculation of energies and half-widths of 198 different Stark states, which are compared with the corresponding results obtained by other authors with the use of other methods. An analysis of this material indicates that the energy values obtained by the phase-integral method are at least as accurate as those obtained by other methods in more than half of the 198 cases. The book presents one of the most comprehensive asymptotic treatments of the Stark effect in atomic hydrogen that have been published./a

This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments of investigations of the properties of ionized gases and their possible applications to nuclear fusion is well known. At the same time optical diagnostic methods have been investigated. The correctness of the measure of the temperature and the electron and ion concentrations depends on our knowledge of the fundamental physical rules which control the broadening of spectral lines. Outside the Doppler effect and the radiation damping, the broadening by collision damping and statistical effect of electrons and ions must be taken into account. (Author).

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.

It is known that when applying perturbation theory in the quantum mechanical treatment of the Stark effect, the perturbation expansion diverges even for very weak fields. It is shown that a plausible modification of the boundary conditions makes the power series convergent at least for those states which areASSOCIATED WITH THE PRINCIPAL QUANTUM NUMBERS N = 1, 2, 3, 4 FOR UP TO ABOUT 10 TO THE 5TH POWER VOLT/CM FIELD STRENGTH. In case of the ground state (n = 1) the radius of convergence obtained will be at least 2.5 (10 to the 6th power volt/cm). (Author).

This book was released on 2009-09-18 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although based on lectures given for graduate students and postgraduates starting in plasma physics, this concise introduction to the fundamental processes and tools is as well directed at established researchers who are newcomers to spectroscopy and seek quick access to the diagnostics of plasmas ranging from low- to high-density technical systems at low temperatures, as well as from low- to high-density hot plasmas. Basic ideas and fundamental concepts are introduced as well as typical instrumentation from the X-ray to the infrared spectral regions. Examples, techniques and methods illustrate the possibilities. This book directly addresses the experimentalist who actually has to carry out the experiments and their interpretation. For that reason about half of the book is devoted to experimental problems, the instrumentation, components, detectors and calibration.

Download or read book The Hydrogen Atom written by S.G. Karshenboim and published by Springer Science & Business Media. This book was released on 2001-06-20 with total page 778 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
