Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Variational Calculation of the Elastic: Scattering of Electrons, by Hydrogen Atoms One of the important problems of upper atmospheric and astrophysical research is the determination of the frequencies of collisions between electrons and atomic systems. Informa tion on this subject can be obtained from a knowledge of the total cross-section, Q, and to some extent from the differential cross-section, (hg), of the collision. The temperatures at which these collisions occur are of such a magnitude that the electron energies are of the order of a fraction of an electron volt, and at these low energies the problems associated with experimental determinations of the cross-sections become complex. Consequently there is a deficiency of experimental data. It is therefore essential to have theoretical methods for calculating the cross-sections.

This book was released on 2017-12-07 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Perturbation Calculation of the Elastic Scattering of Electrons by Hydrogen Atoms If the mass of the proton is taken to be infinite, one can, as an alterna -tive, take as the perturbation simply the interaction between the two electrons. (this we call the symmetric In this case the unperturbed hamiltonian is separable and the initial and final state wave functions corres ponding to it can be exhibited in closed form. This latter procedure is likely to lead to more accurate results than the former, since we include more of the interaction in our unperturbed problem. This advantage will be most pronounced in the calculation of exchange scattering. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Synopsis Variational Methods in Electron-Atom Scattering Theory by : R. K. Nesbet
Download or read book Variational Methods in Electron-Atom Scattering Theory written by R. K. Nesbet and published by Springer. This book was released on 1980-07 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation of scattering phenomena is a major theme of modern physics. A scattered particle provides a dynamical probe of the target system. The practical problem of interest here is the scattering of a low energy electron by an N-electron atom. It has been difficult in this area of study to achieve theoretical results that are even qualitatively correct, yet quantitative accuracy is often needed as an adjunct to experiment. The present book describes a quantitative theoretical method, or class of methods, that has been applied effectively to this problem. Quantum mechanical theory relevant to the scattering of an electron by an N-electron atom, which may gain or lose energy in the process, is summarized in Chapter 1. The variational theory itself is presented in Chapter 2, both as currently used and in forms that may facilitate future applications. The theory of multichannel resonance and threshold effects, which provide a rich structure to observed electron-atom scattering data, is presented in Chapter 3. Practical details of the computational implementation of the variational theory are given in Chapter 4. Chapters 5 and 6 summarize recent appli cations of the variational theory to problems of experimental interest, with many examples of the successful interpretation of complex structural fea tures observed in scattering experiments, and of the quantitative prediction of details of electron-atom scattering phenomena.

Book Synopsis Variational Calculation of Electron Elastic Scattering by Atomic Helium by : Paul Joseph Chernek
Download or read book Variational Calculation of Electron Elastic Scattering by Atomic Helium written by Paul Joseph Chernek and published by . This book was released on 1982 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The elastic-scattering of electrons from atomic helium in the ground state is investigated. It is shown that for low energy incident electrons the scattering problem reduced to solving an ordinary integro-differential equation for the scattering wave-function. A method is discussed to obtain approximate solutions to the integro-differential equation by variational principles. The extremum condition of the variational method is formulated into a general N x N matrix equation which reduces to a 2 x 2 eigen-value matrix problem for the phase-shift of the scattering electron. An algorithm is presented to obtain the collisional cross-section for elastic scattering as a function of incident electron energy. (Author).
