Available in PDF, EPUB and Kindle. Book excerpt: A theory is presented of the recombination of electrons and positive ions in the presence of neutral atoms which act as third bodies, explicit account being taken of the effect of radiative transitions. Comparison is made with the theories of Thomson and of Pitaevskii. Detailed calculations are carried out on recombination in helium gas. It is found that the rate coefficient is very great when the temperature is low and the number density N(He) is high. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This final report describes briefly (a) a microwave system for measuring the electron density in decaying plasmas over t density range of about five thousand, (b) an experimental tube for measuring the value of the mobility of positive ions by means of the transit-time method, and (c) the results obtained during the period of the contract. The studies were confined to the rare gas ions and excellent agreement was found between the value of the mobility of atomic and molecular ions as determined from ambipolar diffusion coefficient measurements and those found by means of the ion transit-time method. The influence of the presence of negative ions on the ambipolar diffusion coefficient of electrons was demonstrated. The recombination coefficients of molecular neon and molecular argon ions were found to be independent of pressure and the values were in excellent agreement with previous studies. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A list of publications of the research performed during the period 1/1/80-6/30/84 is provided. Theoretical research has been conducted a) on ion-ion recombination in high pressure plasmas, b) on the theory of Rydberg collisions with electrons, ions and neutrals, and c) on the theory of ion-molecule collisions at (1 eV-5 keV)/AMU. Papers in these topics (a)-(c) have been written up and published as papers already submitted to AFOSR. In particular, a new and basic theory of ion-ion recombination in a dense gas has been developed from basic microscopic principles. The recombination rate is provided as a function of gas density and time. The theory has been published in papers already submitted to AFOSR. Appendix A of this report contains the published chapter on Theory of Ion-Molecule collisions at (1 eV-50 keV)/AMU.

This book was released on 2012-12-06 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the field of atomic and molecular collisions was left to a handful of practitioners who essentially explored it as a branch of atomic physics and gathered their experimental re sults mainly from spectroscopy measurements in bulk. But in the past ten years or so, all of this has dramatically changed, and we are now witnessing the rapid growth of a large body of research that encompasses the simplest atoms as well as the largest mole cules, that looks at a wide variety of phenomena well outside purely spectroscopic observation, and that finds applications in an unexpectedly broad range of physico-chemical and physical pro cesses. The latter are in turn surprisingly close to very important sectors of applied research, such as the modeling of molecular lasers, the study of isotope separation techniques, and the energy losses in confined plasmas, to mention just a few of them. As a consequence of this healthy state of affairs, greatly diversified research pathways have developed; however, their specialized problems are increasingly at risk of being viewed in isolation, although they are part of a major and extended branch of physics or chemistry. This is particularly true when it comes to the theory of this work -- where well-established methods and models of one subfield are practically unknown to researchers in other subfields -- and, consequently, the danger of wasteful duplication arising is quite real.

This book was released on 2012-12-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sir David Bates celebrated his seventieth birthday on the 18th November 1986. To mark this event a conference was held in the David Bates building at The Queen's University of Belfast on the 17th and 18th November 1986. At this conference ex-students and colleagues of Sir David, who are acknowledged world experts in their field of research, gave in depth reviews of a particular area of atomic and molecular physics. This book on the conference presents a unique account of recent studies in atomic and molecular processes in a wide range of research fields. This volume is dedicated to Sir David by his friends as a token of their affection and respect. It is hoped that it will provide a useful summary of current research in atomic and molecular physics and that it will also show the great contribution which Sir David made to atomic and molecular physics. This conference was supported by the USAF European Office of Aerospace Research and Development who we wish to thank for their generous support. Arthur E.

Available in PDF, EPUB and Kindle. Book excerpt: Although interesting in its own right, due to the ever-increasing use of satellites for communication and navigation, weather in the ionosphere is of great concern. Every such system uses trans-ionospheric propagation of radio waves, waves which must traverse the commonly turbulent ionosphere. Understanding this turbulence and predicting it are one of the major goals of the National Space Weather program. Acquiring such a prediction capability will rest on understanding the very topics of this book, the plasma physics and electrodynamics of the system. Fully updated to reflect advances in the field in the 20 years since the first edition published Explores the buffeting of the ionosphere from above by the sun and from below by the lower atmosphere Unique text appropriate both as a reference and for coursework

Available in PDF, EPUB and Kindle. Book excerpt: Printing on Polymers: Fundamentals and Applications is the first authoritative reference covering the most important developments in the field of printing on polymers, their composites, nanocomposites, and gels. The book examines the current state-of-the-art and new challenges in the formulation of inks, surface activation of polymer surfaces, and various methods of printing. The book equips engineers and materials scientists with the tools required to select the correct method, assess the quality of the result, reduce costs, and keep up-to-date with regulations and environmental concerns. Choosing the correct way of decorating a particular polymer is an important part of the production process. Although printing on polymeric substrates can have desired positive effects, there can be problems associated with various decorating techniques. Physical, chemical, and thermal interactions can cause problems, such as cracking, peeling, or dulling. Safety, environmental sustainability, and cost are also significant factors which need to be considered. With contributions from leading researchers from industry, academia, and private research institutions, this book serves as a one-stop reference for this field—from print ink manufacture to polymer surface modification and characterization; and from printing methods to applications and end-of-life issues. Enables engineers to select the correct decoration method for each material and application, assess print quality, and reduce costs Increases familiarity with the terminology, tests, processes, techniques, and regulations of printing on plastic, which reduces the risk of adverse reactions, such as cracking, peeling, or dulling of the print Addresses the issues of environmental impact and cost when printing on polymeric substrates Features contributions from leading researchers from industry, academia, and private research institutions
