Available in PDF, EPUB and Kindle. Book excerpt: The scattering of fast electrons in nitrogen and argon has been investigated under conditions resulting in approximately 1 to 100 small angle scattering collisions. Experimental measurements have been made of the spatial distribution of the scattered electrons for highly collimated incident electron beams. Electron energies of 20, 40 and 100 keV and gas target thickness of 3 to 1000 torr-cm at room temperature were used. The experimental distributions are much wider than predicted for single scattering and were approximately Gaussian for thick targets with many electron collisions. The dependence of the measured half current beam width on the target thickness varied from a 3/2 power law at small target thicknesses to a 1/2 power law in thick targets. Direct analog Monte Carlo calculations have been made based on a screened cross-section including the large contribution by inelastic collisions at very small scattering angles. Despite the approximate nature of the cross-section data the calculated spatial distributions of scattered electrons agree well with the experimental results except at the smallest target thicknesses where the calculated distributions are wider than the experimental results.

This book was released on 2012-12-06 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron energy loss spectroscopy (ELS) is a vast subject with a long and honorable history. The problem of stopping power for high energy particles interested the earliest pioneers of quantum mechanics such as Bohr and Bethe, who laid the theoretical foun dations of the subject. The experimental origins might perhaps be traced to the original Franck-Hertz experiment. The modern field includes topics as diverse as low energy reflection electron energy loss studies of surface vibrational modes, the spectroscopy of gases and the modern theory of plasmon excitation in crystals. For the study of ELS in electron microscopy, several historically distinct areas of physics are relevant, including the theory of the Debye Waller factor for virtual inelastic scattering, the use of complex optical potentials, lattice dynamics for crystalline specimens and the theory of atomic ionisation for isolated atoms. However the field of electron energy loss spectroscopy contains few useful texts which can be recommended for students. With the recent appearance of Raether's and Egerton's hooks (see text for references), we have for the first time both a comprehensive review text-due to Raether-and a lucid introductory text which emphasizes experimental aspects-due to Egerton. Raether's text tends to emphasize the recent work on surface plasmons, while the strength of Egerton's book is its treatment of inner shell excitations for microanalysis, based on the use of atomic wavefunctions for crystal electrons.

This book was released on 1965 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation some basic relationships concerning the scattering of light from particles which are very small compared to wavelengths of interest--specifically free electrons, ions, atoms and simple molecules--are examined from a consistent application of quantum perturbation theory to a many body system. Of major concern are particles in gaseous or plasma systems, although many of the results may have broader validity. For the most part attention is confined to nonresonance, linear, single scattering. Higher ordered corrections to the scattering cross section which arise from the variation of the refractive index from unity are neglected and the possible effects of variations in the intensity of incident radiation over distances comparable to wavelengths of interest are not considered in detail. The results obtained under these conditions appear to retain wide limits of applicability are discussed. However, where necessary, all of these conditions can be relaxed to varying degrees through procedures which are mentioned. Among the major results obtained are, first, a consistent and informative derivation of the dependence of light scattering in gases on particle-particle interactions; second, a comparatively simple derivation of the angular distribution of the scattered light; third, detailed relationships between scattering cross sections and oscillator strengths which permit the calculation of Rayleigh and Raman scattering cross sections under appropriate conditions; and fourth, a relationship between familiar quantum expressions for scattering cross sections and refractive indices.

Available in PDF, EPUB and Kindle. Book excerpt: There is a unity to physics; it is a discipline which provides the most fundamental understanding of the dynamics of matter and energy. To understand anything about a physical system you have to interact with it and one of the best ways to learn something is to use electrons as probes. This book is the result of a meeting, which took place in Magdalene College Cambridge in December 2001. Atomic, nuclear, cluster, soHd state, chemical and even bio- physicists got together to consider scattering electrons to explore matter in all its forms. Theory and experiment were represented in about equal measure. It was meeting marked by the most lively of discussions and the free exchange of ideas. We all learnt a lot. The Editors are grateful to EPSRC through its Collaborative Computational Project program (CCP2), lOPP, the Division of Atomic, Molecular, Optical and Plasma Physics (DAMOPP) and the Atomic Molecular Interactions group (AMIG) of the Institute of Physics for financial support. The smooth running of the meeting was enormously facilitated by the efficiency and helpfulness of the staff of Magdalene College, for which we are extremely grateful. This meeting marked the end for one of us (CTW) of a ten-year period as a fellow of the College and he would like to take this opportunity to thank the fellows and staff for the privilege of working with them.
