Available in PDF, EPUB and Kindle. Book excerpt: The broad development of spectroscopy in our country and, in particular, the extensive industrial applications of methods of spectral analysis make the need for basic reference literature a pressing one. Tables of spectral lines, as basic, primary material necessary for the identifica tion of spectra, are the most important of these reference books. The need for such tables is acutely felt by all who work in spectroscopy, and numerous requests for such a book have been received by the Commission on Spectroscopy of the Academy of Sciences of the USSR. On the world book market there are fairly complete tables that cover a very great number of spectral lines and that have been complied rather carefully, although they are not free of errors. Tables of this kind are undoubtedly necessary in general spectroscopic research and must be included among the reference books of large scientific institutions. But the number of workers who need such complete tables is comparatively limited. Therefore, after long discussion it was deemed impractical to republish these tables.
Download or read book Polarization in Spectral Lines written by M. Landi Degl'Innocenti and published by Springer Science & Business Media. This book was released on 2006-05-17 with total page 899 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific research based on spectropolarimetric techniques is undergoing a phase of rapid growth. Instruments of unprecedented sensitivity are nowadays available, particularly for solar observations. To fully exploit the rich diagnostic content of such observations, it is necessary to understand the physical mechanisms involved in the generation and transfer of polarized radiation in astrophysical (or laboratory) plasmas. After an introductory part based on classical physics, this book tackles the subject by a rigorous quantum-mechanical approach. The transfer equations for polarized radiation and the statistical equilibrium equations for the atomic density matrix are derived directly from the principles of Quantum Electrodynamics. The two sets of equations are then used to present a number of applications, mainly concerning the diagnostics of solar magnetic fields. This book is primarily addressed to scientists working in the field of spectropolarimetry. It may also serve as a textbook for a course at the graduate or advanced undergraduate level.
Download or read book Tables of Spectral Lines of Neutral and Ionized Atoms written by A. R. Striganov and published by Springer Science & Business Media. 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.

Download or read book Handbook of Spectral Lines in Diamond written by Bernhard Dischler and published by Springer Science & Business Media. This book was released on 2012-06-13 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a breakthrough in the understanding of the large number of spectral lines in diamond. Data on more than 2000 lines and bands are presented in 200 tables, including many unpublished results. With a novel organization scheme, the search for a specific line is greatly simplified as a benefit for researchers and students. In order to meet the interest in the understanding of the spectra, structure assignments for 80 % of the lines are given, of which 15 % only were published before. The majority of the structures for the 300 centers is explained in most cases for the first time. A key instrument in the interpretation is the analysis by donor-acceptor pair transitions. In a special chapter 95 such centers are listed and discussed, of which only two have been published before, the first one by the present author in 1994.
Download or read book Pressure Broadening of Spectral Lines written by Peter Joseph Rayer and published by Cambridge University Press. This book was released on 2020-08-06 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting the quantum mechanical theory of pressure broadening and its application in atmospheric science, this is a unique treatment of the topic and a useful resource for researchers and professionals alike. Rayer proceeds from molecular processes to broad scale atmospheric physics to bring together both sides of the problem of remote sensing. Explanations of the relationship between a series of increasingly general theoretical papers are provided and all key expressions are fully derived to provide a firm understanding of assumptions made as the subject evolved. This book will help the atmospheric physicist to cross into the quantum world and appreciate the more theoretical aspects of line shape and its importance to their own work.

Download or read book Radiation Transport in Spectral Lines written by R.G. Athay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: The usual book on the theory of spectral line formation begins with an in-depth dis cussion of radiation transfer, including the elegant methods of obtaining analytical solutions for special cases, and of the physics of line broadening. Neither of those features will be found in this book. It is assumed that the reader is already familiar with the essentials of transport theory and of line broadening and is ready to investi gate some of the particular applications of the theory to the flow of line photons through the outer layers of a star, or other tenuous media. The main thrust of this book is toward the compilation and presentation of a vast quantity of computational material available to the author in the form of computer output. The material presented represents a highly filtered sample of the published work in this subject plus an extensive set of previously unpublished results. To present large quantities of computer output in an intelligible and efficient way is a difficult task, for which I have found no really satisfactory solution. Chapters III and IV, in particular, contain almost exclusively this type of presentation. The reader may find these chapters somewhat tedious because of the level of condensation of the material. I have tried to reach a reasonable balance between over condensation and excessive detail, which in the long run may be irrelevant.

Download or read book A Search for Spectral Lines from WIMP Annihilation in the Milky Way Using the Fermi Large Area Telescope written by Yvonne Vasetta Edmonds and published by Stanford University. This book was released on 2011 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most popular class of dark matter candidates is the class of weakly-interacting massive particles (WIMPs). The Fermi Large Area Telescope has the possibility of indirectly detecting WIMPs by the flux from their annihilation/decay products. When a WIMP annihilates or decays directly into a photon gamma and another particle Y the photons are monochromatic. Detection of the resulting spectral line(s) would provide convincing evidence for particulate dark matter and could provide the WIMP mass. In the case of no detection, knowledge of the dark matter distribution can be used to place limits on the annihilation cross section and lifetime for the WIMP(s) to Y-gamma channel. We present the spectrum from 4.8 to 264 GeV and spectral line flux upper limits, obtained from a subset of this spectrum, from 7 to 200 GeV. The spatial region of the dataset covers a large portion of the sky, the high latitudes plus the Galactic Center. We report upper limits on the WIMP cross sections for annihilation to gamma-gamma and Z-gamma and lower limits on the WIMP lifetime for decay to gamma-neutrino. We discuss the implications of the spectrum and line flux limits for several dark matter models with optimistic branching ratios for photon channels.
