Download or read book Spectral Line Broadening by Plasmas written by Hans Griem and published by Elsevier. This book was released on 2012-12-02 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral Line Broadening by Plasmas deals with spectral line broadening by plasmas and covers topics ranging from quasi-static approximation and impact approximation to intermediate approximations and correlation effects. Experimental results for hydrogen lines, lines with forbidden components, and ionized helium lines are presented. Applications such as density and temperature measurements are also considered. Comprised of four chapters, this volume begins with an overview of the effects of electric fields from electrons and ions (both acting as point charges) on spectral line shapes. The next chapter surveys theoretical work, paying particular attention to quasi-static, impact, and intermediate approximations as well as correlation effects. Stark broadening experiments are then discussed, with special emphasis on experiments capable of checking the accuracy or validity limits of the various approximations. The final chapter is devoted to applications in laboratory plasma physics and astronomy, focusing on density and temperature measurements and opacity calculations as well as the analysis of stellar atmospheres, amplitudes and spectra of plasma waves, and radio frequency lines. This book should appeal to students, practitioners, and researchers in pure and applied physics.

Book excerpt: Experimental and theoretical studies of Stark broadening of spectral lines in plasmas are the cornerstone of a large number of spectroscopic diagnostics of laboratory and astrophysical plasmas. As such, they are very important both fundamentally and practically, the latter being due to the numerous practical applications of plasmas. Examples are studies dealing with: controlled thermonuclear fusion (that would provide a virtually unlimited source of energy), plasma-based lasers for medical and other purposes, technological microwave discharges (especially those used for manufacturing microchips), a better understanding of solar activity, other astrophysical objects (white dwarfs, flare stars, and so on). The book reviews advances in this area achieved in recent years and presents new original papers building on these advances.

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.

This book was released on 2022-12-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stark broadening is dominant mechanism of broadening for spectral lines in high-energy plasma. This book focuses on research of stellar plasma, although the results can be used in a study of laboratory plasma as well. Importance of Stark broadening of spectral lines for analysis, interpretation and synthesis of the star spectra, diagnostics, analysis and modeling of stellar plasma is considered as well as the significance of these results for research laboratory, fusion and technological plasma or laser physics. The aim is to determine the previously unknown Stark broadening parameters of the spectral lines of transition metals and lanthanides that do not exist in the literature yet, neither measured by laboratory methods nor theoretically determined, for single electrically charged ions (Co II), double electrically charged ions (Lu III), and triple electrically charged ions (Zr IV), in order to study the impact of line broadening on spectra of hot stars and white dwarfs.

Download or read book Plasma Spectroscopy written by Takashi Fujimoto and published by Clarendon Press. This book was released on 2004-06-17 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the characteristics of optical radiation, or a spectrum, emitted by various plasmas. In plasma, the same atomic species can produce quite different spectra, or colours, depending on the nature of the plasma. This book gives a theoretical framework by which a particular spectrum can be interpreted correctly and coherently. The uniqueness of the book lies in its comprehensive treatment of the intensity distribution of spectral lines and the population density distribution among the atomic levels in plasmas. It is intended to provide beginners with a good perspective of the field, laying out the physics in an extremely clear manner and starting from an elementary level. A useful feature of the book is the asterisked sections and chapters which can be skipped by readers who only wish to gain a quick and basic introduction to plasma spectroscopy. It will also be useful to researchers working actively in the field, acting as a guide for carrying out experiments and interpreting experimental observations.

Download or read book Principles of Plasma Spectroscopy written by Hans R. Griem and published by . This book was released on 1997 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive description of the theoretical foundations and experimental applications of spectroscopic methods in plasma physics research. It introduces the classical and quantum theory of radiation, with detailed descriptions of line strengths and high density effects, and describes theoretical and experimental aspects of spectral line broadening. The book illustrates the concepts of continuous spectra, level kinetics and cross sections, thermodynamic equilibrium relations, radiative energy transfer, and radiative energy losses. The basics of plasma spectroscopy to density and temperature measurements and to the determination of some other plasma properties are also explored. Over one thousand references not only guide the reader to original research covered in the chapters, but also to experimental details and instrumentation.

Download or read book Stark Broadening in Laser produced Plasmas written by Lawrence A. Woltz and published by . This book was released on 1982 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a study of the Stark broadening of spectral lines emitted by highly charged ions in a hot, dense plasma. The line broadening calculations of Tighe and Hooper, in which the dipole approximation was used for the interaction between the radiating ions and perturbing electrons, are extended by retaining the full Coulomb radiator-perturbing electron interaction . Electron broadening is treated to second order in the radiator-perturbing electron interaction; ion broadening is treated by a static ion microfield probability distribution . Perturbing electrons are treated quantum mechanically through Coulomb wavefunctions to account for the charged radiator . Line profiles from this calculation are slightly broader than those calculated using the dipole approximation . The near agreement of these results is partly fortuitous in that the dipole approximation overestimates the dipole part of the Coulomb interaction for perturbers close to the radiator, partially compensating for the neglected multipoles of the interaction . This full Coulomb calculation of the dynamic line shift due to perturbing electrons results in a significantly smaller shift than that obtained when the dipole approximation for the radiator-perturbing electron interaction is used . For an Argon Lyman B line calculated for the plasma conditions of 10 electrons/cm and 800 eV, this shift is about 0.03 Ryd toward lower energies, and it causes no noticeable asymmetry in the line. The effect of the dynamic shift on the line is considerably smaller than that of the static (plasma polarization) shift calculated by Skupsky, which causes an asymmetry in the p line, with the red wing having the greater intensity. For an Argon Lyman B line, the significance of ion-radiator and electron-radiator perturbation matrix elements between the initial radiator states, principal quantum number = 3, and the states of the nearest adjacent energy level, principal quantum number = 4, is examined . The electron-radiator matrix elements are found to give a small additional broadening of the line; the ion-radiator matrix elements are found to cause a significant nonlinear Stark shift of the radiator energy levels. This shift causes the line to be asymmetric, with the blue peak having greater intensity than the red peak and the red wing having greater intensity than the blue wing.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a compact yet comprehensive overview of recent developments in collisional-radiative (CR) modeling of laboratory and astrophysical plasmas. It describes advances across the entire field, from basic considerations of model completeness to validation and verification of CR models to calculation of plasma kinetic characteristics and spectra in diverse plasmas. Various approaches to CR modeling are presented, together with numerous examples of applications. A number of important topics, such as atomic models for CR modeling, atomic data and its availability and quality, radiation transport, non-Maxwellian effects on plasma emission, ionization potential lowering, and verification and validation of CR models, are thoroughly addressed. Strong emphasis is placed on the most recent developments in the field, such as XFEL spectroscopy. Written by leading international research scientists from a number of key laboratories, the book offers a timely summary of the most recent progress in this area. It will be a useful and practical guide for students and experienced researchers working in plasma spectroscopy, spectra simulations, and related fields.

Download or read book Quantum Mechanics of One and Two Electron Atoms written by Hans A. Bethe and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly all of this book is taken from an article prepared for a volume of the Encyclopedia of Physics. This article, in turn, is partly based on Dr. Norbert Rosenzweig's translation of an older article on the same subject, written by one of us (H.A.B.) about 25 years ago for the Geiger-Scheel Handbuch der Physik. To the article written last year we have added some Addenda and Errata. These Addenda and Errata refer back to some of the 79 sections of the main text and contain some misprint corrections, additional references and some notes. The aim of this book is two-fold. First, to act as a reference work on calcu lations pertaining to hydrogen-like and helium-like atoms and their comparison with experiments. However, these calculations involve a vast array of approximation methods, mathematical tricks and physical pictures, which are also useful in the application of quantum mechanics to other fields. In many sections we have given more general discussions of the methods and physical ideas than is necessary for the study of the H- and He-atom alone. We hope that this book will thus at least partly fulfill its second aim, namely to be of some use to graduate students who wish to learn "applied quantum mechanics". A basic knowledge of the principles of quantum mechanics, such as given in the early chapters of Schiff's or Bohm's book, is presupposed.
