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.

Atomic and Molecular Processes describes radiative and collisional processes involving atoms or molecules. Organized into 21 chapters, this book emphasizes the developments in these processes stimulated by the growth of interest in space science, astrophysics, and plasma physics. The book initially discusses the general theory of magnetic dipole and electric quadrupole radiation and the calculations and observations on individual atoms, as well as the forbidden transitions. The text then explores general topics on forbidden and allowed lines and bands; photoionization; photodetachment; recombination and attachment; elastic and inelastic scattering of electron; and energy loss by slow electrons. Discussions on collision broadening of spectral features and encounters between atomic systems including range, energy loss, excitation, ionization, detachment, charge transfer, elastic scattering, mobility, diffusion, relaxation in gases, and chemical reactions are provided in other chapters. A chapter is devoted to the use of high-temperature shock waves, and accounts of other main experimental methods are given.

The Stark broadening of spectral lines in plasmas belongs to the highest level of plasma spectroscopy and is consequently its most complicated subject. Therefore, physics of the Stark broadening can be best understood for spectral lines of one-electron systems: hydrogen atoms and hydrogenlike ions. This book presents sophisticated analytical advances into this problem, thus yielding a profound physical insight. The book contains also the Tables of Stark widths of hydrogen and deuterium lines in plasmas. These Tables are based on the most advanced theory/code, proven by the comparison with the benchmark experiments. Analytical and numerical results presented in the book have very broad, interdisciplinary practical applications across various areas of physics and technology, such as: · Magnetically-controlled fusion · Laser-controlled fusion · Powerful Z-pinches used for producing x-ray and neutron radiation, ultra-high pulsed magnetic fields, and for x-ray lasing · X-ray lasers · Low-temperature technological discharges for plasma processing · Cold Rydberg plasmas (a new research area that bridges the gap between atomic physics and plasma physics) · Astrophysics, including solar physics.

Physics, Formation and Evolution of Rotating Stars

Rotation is ubiquitous at each step of stellar evolution, from star formation to the final stages, and it affects the course of evolution, the timescales and nucleosynthesis. Stellar rotation is also an essential prerequisite for the occurrence of Gamma-Ray Bursts. In this book the author thoroughly examines the basic mechanical and thermal effects of rotation, their influence on mass loss by stellar winds, the effects of differential rotation and its associated instabilities, the relation with magnetic fields and the evolution of the internal and surface rotation. Further, he discusses the numerous observational signatures of rotational effects obtained from spectroscopy and interferometric observations, as well as from chemical abundance determinations, helioseismology and asteroseismology, etc. On an introductory level, this book presents in a didactical way the basic concepts of stellar structure and evolution in "track 1" chapters. The other more specialized chapters form an advanced course on the graduate level and will further serve as a valuable reference work for professional astrophysicists.

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.

Electromagnetic Fluctuations In Plasma

ISBN: 0323158382

Electromagnetic Fluctuations in Plasma focuses on the theoretical investigation of the electromagnetic properties of a plasma (an ionized gas). The manuscript first takes a look at the general theory of fluctuations and electromagnetic fluctuations in media with space-time dispersion. Discussions focus on spectral distribution of the fluctuations and energy dissipation in the medium; dielectric and magnetic permittivities in a medium with spatial dispersion; current, charge, and field fluctuations in a medium; and inversion of the fluctuation-dissipation theorem. The text then examines the electrodynamic properties of an electron plasma and electromagnetic fluctuations in an electron plasma. The publication ponders on fluctuations in an electron-ion plasma and electron plasma in a magnetic field. Topics include plasma dielectric permittivity tensor in a magnetic field; longitudinal plasma oscillations in a magnetic field; fluctuations in charge and current densities in an equilibrium electron-ion plasma; and electron and ion density fluctuations in an equilibrium plasma. The text also tackles the passage of charged particles through plasma and dynamic friction and diffusion coefficients in a plasma. The book is a dependable reference for readers interested in the study of the electromagnetic properties of a plasma.

Specifically, the articles include quasars, Seyfert galaxies, active galactic nuclei, the solar chromosphere and corona, galactic HII regions, circumstellar shells, interstellar gas, supernova remnants and interstellar clouds. The book includes an account of the basic aspects of spectroscopy in a chapter on laboratory astrophysics. The book was stimulated by the extraordinary contributions to astronomical spectroscopy of Leo Goldberg, and is dedicated to him. Throughout, this book is written with the needs of students in astronomy and astrophysics in mind. Each chapter includes a summary or conclusions about the future direction of research. Furthermore there are extensive bibliographies. This textbook is therefore an excellent introduction to research in astrophysics and it will act as a pathfinder to the primary literature.
