Available in PDF, EPUB and Kindle. Book excerpt: Line widths have been measured on spectra from implosions with the Gamble II generator. The K-shell transitions from sodium ions were observed with a curved crystal x-ray spectrograph and imaged with a pinhole camera. The various contributions to spectral line broadening were analyzed. The conclusion is that the line widths were comprised essentially of a source broadening due to the finite plasma size and a plasma broadening due to the ion motion during the implosion final stage. Despite the comparable contribution from both effects, under our conditions of observation, it is possible to derive an upper limit for the ion velocity to account for the large line widths observed. Keywords: Sodium implosions, X ray spectroscopy, Plasma parameters.

This book was released on 2013-11-21 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tables of Spectral Lines of Neutral and Ionized Atoms was first published in Moscow in 1966. All misprints and errors that have come to our attention have been corrected, and additions based on journal articles have been made for the Plenum Press edition. In particular, additions have been made in the tables for Li (4], C I [1], N I (1], N IV [12], and N V [14]. Such highly important spectra as those of N IV, NV, 0 IV, 0 V, and 0 VI in the visible and partially in the ultraviolet regions have, until recently, re ceived almost no attention in the laboratory. The tables of these spectra in clude astrophysical data from B. Edlen (Z. Astrophys. , 7:378, 1933) and C. E. Moore (A Multiplet Table of Astrophysical Interest, Part I, N. B. S. , 1945) with rather rough estimates of the wavelengths of the spectral lines. But as the spectra of highly ionized atoms have been studied in the laboratory, these values have been determined more precisely, and we have striven to incorporate them in the American edition of the book. For the spectra of N IV and NV, we have employed the recent, comprehensive papers of R. Hallin (Arkiv for Fysik, 32:201, 1966; 31:511, 1966), in which the system of energy levels was refined and expanded, and many classified lines in the visible, ordinary ultra violet, and vacuum ultraviolet regions are cited.

Available in PDF, EPUB and Kindle. Book excerpt: Spectral lines, widths, and shapes are powerful tools for emitting/absorbing gas diagnostics in different astrophysical objects (from the solar system to the most distant objects in the universe—quasars). On the other hand, experimental and theoretical investigations of laboratory plasma have been applied in spectroscopic astrophysical research, especially in research on atomic data needed for line shape calculations. Data on spectral lines and their profiles are also important for diagnostics, analysis, and the modelling of fusion plasma, laser-produced plasma, laser design and development, and various plasmas in industry and technology, like light sources based on plasmas or the welding and piercing of metals by laser-produced plasma. The papers from this book can be divided into four groups: 1. stark broadening data for astrophysical and laboratory plasma investigations; 2. applications of spectral lines for astrophysical and laboratory plasma research; 3. spectral line phenomena in extragalactic objects, and 4. laboratory astrophysics results for spectra investigation. The reviews and research papers, representing new research on the topics presented in this book, are of interest for specialists and PhD students. We hope that the present book will be useful and interesting for scientists interested in the investigation of spectral line shapes and will contribute to the education of young researchers and PhD students.

Available in PDF, EPUB and Kindle. Book excerpt: The biennial ICSLS conferences review the most recent theoretical and experimental advances in both fundamental and applied work dealing with the formation of spectral line profiles, the underlying physical processes, and the use of line shape analysis for diagnostic applications. Spectral line shapes and shifts are affected by the interactions between atoms, molecules, ions, electrons and photons. Therefore, their measurement and interpretation provides information on the physical properties of all kinds of material systems, from astrophysical and nuclear-fusion plasmas to superfluid helium droplets. Topics discussed in these proceedings include dense plasmas, hydrogen plasma broadening, asymmetry, non-hydrogenic line profiles, plasma-diagnostic and other applications, general theory, high-resolution spectroscopy, alkali-doped helium clusters, molecules and atoms, optical collisions, collision-induced effects, and related topics.
