Download or read book Photoabsorption and Photoionization Cross Sections of O, O2, and N2 for Photoelectron Production Calculations: A Compilation of Recent Laboratory Measurements written by Robert R. Conway and published by . This book was released on 1988 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: REcent laboratory measurements of photoionization cross section s and ion state branching ratios for atomic oxygen, molecular nitrogen and molecular oxygen are combined with theoretical cross sections for soft x-ray absorption and tabulated for use in atmospheric photoionization calculations. The most important changes from earlier compilations for aeronomical calculations is a factor of approximately two reduction in the absorption and ionization cross section of atomic oxygen between 100 angstroms and 300 angstroms, and a detailed treatment of partial cross sections for the dissociating state of N2 and O2. The results are tabulated on the wavelength scale of the Atmospheric Explorer solar reference spectrum SC 21REFW (Hinteregger et al., 1981).

Book Synopsis The Upper Mesosphere and Lower Thermosphere by : R. M. Johnson
Download or read book The Upper Mesosphere and Lower Thermosphere written by R. M. Johnson and published by American Geophysical Union. This book was released on 1995-01-09 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 87. This volume provides a review of progress made in recent years in experimental and theoretical investigation of the upper mesosphere and lower thermosphere and coupling between these regions and the ionosphere. Detailed study of the mesosphere/lower thermosphere/ionosphere (MLTI) region has historically been difficult because of its relative inaccessibility to direct measurement techniques and the complex and highly coupled processes which occur there. Although we have still not successfully unraveled all these complex interactions, we have made significant recent progress toward a fuller understanding of the basic state of the MLTI and of the dominant wave and coupling processes. This monograph includes a set of tutorial papers, which review our current understanding of aspects of the MLTI. These tutorials are interspersed with a selection of papers describing research progress on various topics of current interest in this region. The book should therefore be useful both to the newcomer, as an introduction to this field of research, and to the more experienced researcher, providing an overview of research in progress as well as a convenient reference collection of papers describing our current understanding.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 66. During the week of June 4-8, 1990, a Chapman Conference on Venus and Mars: Atmospheres, Ionospheres and Solar Wind Interactions was held at Balatonfüred, Hungary. The meeting was coorganized by J. G. Luhmann and M. Tatrallyay, under the auspices of the AGU and the Hungarian Academy of Sciences. Aprroximately 85 participants attended some 72 presentations in oral and poster form. The topics on which the sessions focused included atmosphere evolution, present atmospheres, exospheres and ionospheres, solar wind interactions, and past and future missions. The international and multidisciplinary makeup of the audience provided the basis for a wide range of discussions and brought out a number of remaining controversies and questions to be answered by future research.

Book Synopsis Atomic and Molecular Photoabsorption by : Joseph Berkowitz
Download or read book Atomic and Molecular Photoabsorption written by Joseph Berkowitz and published by Academic Press. This book was released on 2015-03-27 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic and Molecular Photoabsorption: Partial Cross Sections is a companion work to Joseph Berkowitz's earlier work, Atomic and Molecular Photoabsorption: Absolute Total Cross Sections, published with Academic Press in 2002. In this work Joseph Berkowitz selected the "best" absolute partial cross sections for the same species as included in the companion work. A contrast, however, is that photoabsorption measurements, being of order I/Io, do not require the most intense light sources, whereas acquiring data on the products of light interactions with gaseous matter (ions, electrons, various coincidence measurements) has benefited significantly with the arrival of second- and third-generation synchrotrons. The newer devices have also extended the energy range of the light sources to include the K-shells of the species discussed here. The newer light sources encouraged experimentalists to develop improved instrumentation. Thus, the determination of partial cross sections continues to be an active field, with more recent results in some cases superseding earlier ones. Where the accuracy of the absolute partial cross sections is deemed sufficient (less than five percent), numerical tables are included in this new work. In other cases, the available data are presented graphically. Includes data on atoms, diatomic molecules, triatomic molecules, and polyatomic molecules Written by world-leading pioneer in the field of photoionization mass spectrometry Very clear presentation of the useful, quantitative information in both tables and graphs
Book Synopsis Determination of Partial Photoionization Cross Sections by Photoelectron Spectroscopy by : A. J. Blake
Download or read book Determination of Partial Photoionization Cross Sections by Photoelectron Spectroscopy written by A. J. Blake and published by . This book was released on 1967 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: A photoelectron energy spectrometer was used to determine partial photoionization cross sections of molecular oxygen, nitrogen and water vapour for monochromatic incident radiation in the wavelength range 584 - 900A. For each gas, cross sections were determined for transitions to particular ionic states which were identified by measuring the corresponding photoelectron energy. For molecular oxygen, cross sections were determined for transitions to the X(2)Pi-g, (a(4)Pi-u + A(2)Pi-u) b(4) Sigma( - )g and (2)Sigma( - )g states of O2(+) and at incident wavelengths longer than 680A a process of fluorescent autoionization involving quasi-stable states of the neutral oxygen molecule was also observed. Molecular nitrogen cross sections corresponding to transitions to the X(2)Sigma(+)g, A(2)Pi-u and B(2)Sigma(+)u states of N2(+) were determined. For water vapour, cross sections corresponding to transitions to the (2)B1 and (2)A1 states of H2O(+) were observed in addition to processes of dissociative ionization. In all cases the measurements illustrate the competition between various modes of decay which are energetically possible for incident radiation of a given wavelength. (Author).

Book Synopsis Cities and Their Vital Systems by : Advisory Committee on Technology and Society
Download or read book Cities and Their Vital Systems written by Advisory Committee on Technology and Society and published by National Academies Press. This book was released on 1989 with total page 1298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
