This book was released on 1977 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the velocity dependence of the absolute total ionization cross section of argon atoms upon impact with selected metastable states of helium atoms are reported. A low voltage D.C. discharge was used as the source of the excited atoms, and a rotating slotted disk selector was used for velocity selection of the excited atoms. Selection of th electronic spin state of the excited atoms was accomplishe by irradiation of the excited atoms with radiation from a helium d i s cha r g e 1 amp . Ionization of the argon target atoms by metastable. heliui atoms was studied by the gas cell technique in which all ionization products were collected. The ionization measurements were of sufficient precision to allow simultaneous determination of the cross section and the secondary electron ejection efficiency for each metastable state of helium. The secondary electron ejection efficiency of triplet me tas table helium atoms on an electroplated gold surface was determined to be 0.440 + 0.018 in the presence of argon gas. The secondary electron ejection efficiency of singlet: metastable atoms was determined to be 0.582 + 0.024 under similar conditions. The local ionization cross section for the He(2 S)-Ar system was found to increase almost linearly from S.8 A to 2.1.95 £ with an increase of relative velocity from 1162 from 9.8?? to 26.2 K 2 with an increase in relative m/sec to 2787 in/ sec. After an initial increase, of the cross section velocity from 989 m/sec to 2058 m/sec, the velocity dependence of the cross: section of the He (2 S)-Ar system entered a saturation region in which the cress section changed very little with relative velocity. The collision energy dependence of the He(2"S)-Ar system was also used to determine the values of adjustable parameters present in a current theory based on the potential curve model for Penning and associative Pennine ionization.

Download or read book Auger Electron Spectroscopy written by Donald T. Hawkins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Auger electron spectroscopy is rapidly developing into the single most powerful analytical technique in basic and applied science.for investigating the chemical and structural properties of solids. Its ex plosive growth beginning in 1967 was triggered by the development of Auger analyzers capable of de tecting one atom layer of material in a fraction of a second. Continued growth was guaranteed firstly by the commercial availability of apparatus which combined the capabilities of scanning electron mi croscopy and ion-mill depth profiling with Auger analysis, and secondly by the increasing need to know the atomistics of many processes in fundamental research and engineering applications. The expanding use of Auger analysis was accompanied by an increase in the number of publications dealing with it. Because of the developing nature of Auger spectroscopy, the articles have appeared in many different sources covering diverse disciplines, so that it is extremely difficult to discover just what has or has not been subjected to Auger analysis. In this situation, a comprehensive bibliography is obviou-sly useful to those both inside and outside the field. For those in the field, this bibliography should be a wonderful time saver for locating certain references, in researching a particular topic, or when considering various aspects of instrumentation or data analysis. This bibliography not only provides the most complete listing of references pertinent to surface Auger analysis available today, but it is also a basis for extrapolating from past trends to future expectations.

Available in PDF, EPUB and Kindle. Book excerpt: The principal goal of this book is to provide state-of-the-art coverage of the non-relativistic three- and four-body theories at intermediate and high energy ion-atom and ion-molecule collisions. The focus is on the most frequently studied processes: electron capture, ionization, transfer excitation and transfer ionization. The content is suitable both for graduate students and experienced researchers. For these collisions, the literature has seen enormous renewal of activity in the development and applications of quantum-mechanical theories. This subject is of relevance in several branches of science and technology, like accelerator-based physics, the search for new sources of energy and high temperature fusion of light ions. Other important applications are in life sciences via medicine, where high-energy ion beams are used in radiotherapy for which a number of storage ring accelerators are in full operation, under construction or planned to be built worldwide. Therefore, it is necessary to review this field for its most recent advances with an emphasis on the prospects for multidisciplinary applications.This book is accompanied by Interdisciplinary Research on Particle Collisions and Quantitative Spectroscopy Volume 2 - Fast Collisions of Light Ions with Matter: Charge Exchange and Ionization.
