Available in PDF, EPUB and Kindle. Book excerpt: The scattering at 57.9 deg of one million volt electrons and positrons by thin foils has been investigated experimentally from two points of view: (1) to compare the cross section for elastic nuclear scattering of positrons with that of electrons, and (2) to look for inelastically scattered electrons which have suffered large energy losses. The first is of interest because theory predicts a large difference between positron and electron nuclear scattering resulting from spin orbit coupling. The second is of interest because there have been many experimental reports of such inelastic scattering but no satisfactory theoretical reason for the effect. Values were obtained for the ratio of the electron scattering cross section to that of positrons at three different energies in the one million volt region for foils of platinum and copper. The results were in rough agreement with theoretical predictions, with a consistent deviation which may be attributed to the failure of the theory to include the effects of screening. The investigation of inelastic scattering failed to observe any effect in foils of aluminum, copper, platinum and lead. (Author).

Download or read book Electron Scattering From Complex Nuclei V36A written by Herbert Uberall and published by Academic Press. This book was released on 2012-12-02 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron Scattering from Complex Nuclei, Part A covers the historical phases of experimental development in elastic and inelastic electron scattering. This five-chapter text presents the logical development of the underlying theory of electron scattering. After briefly discussing the history of electron scattering from nuclei, this book goes on describing the theory of elastic scattering from a point nucleus, both with Born approximation and the accurate solution of the Dirac equation, as well as the corresponding experiments. The following chapter considers the analysis of nuclear charge distributions experiments using Born cross section and phase-shift methods. A chapter is devoted to the complete elastic and inelastic Born theory. This chapter also deals with the derivation of a theorem on the general form of the electron-nucleus scattering cross section, with an emphasis on the influence of the neglected transverse interaction on the cross section. The last chapter presents the status of elastic scattering along with some topics in muonic atoms that also determine nuclear charge densities. This book will be of great benefit to physicists, researchers, and graduate students who are interested in nuclear structure problems.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Positrons can be used to study metallic defects. Positron annihilation experiments have been carried out to identify the defects in complex oxides. Positrons have also been used to study the Bose–Einstein condensation (BEC). Ps-BEC can be used to measure antigravity using atomic interferometers. This Special Issue hopes to bring awareness of the various aspects of positron interactions to the larger physics communities. We invite authors to submit articles from all areas of physics.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the considerable progress recently achieved in the understanding of nucleon and nuclear structure by using high energy electrons as a probe. A collection of papers discusses in detail the new frontiers of this field. Experimental and theoretical articles cover topics such as the structure of the nucleon, nucleon distributions, many-body correlations, non-nucleonic degrees of freedom and few-body systems. This book is an up-to-date introduction to the research planned with continuous beam electron accelerators.

This book was released on 2018-10-13 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of protons and neutrons, or "nucleons"â€"the building blocks of atomic nucleiâ€"has advanced dramatically, both theoretically and experimentally, in the past half century. A central goal of modern nuclear physics is to understand the structure of the proton and neutron directly from the dynamics of their quarks and gluons governed by the theory of their interactions, quantum chromodynamics (QCD), and how nuclear interactions between protons and neutrons emerge from these dynamics. With deeper understanding of the quark-gluon structure of matter, scientists are poised to reach a deeper picture of these building blocks, and atomic nuclei themselves, as collective many-body systems with new emergent behavior. The development of a U.S. domestic electron-ion collider (EIC) facility has the potential to answer questions that are central to completing an understanding of atoms and integral to the agenda of nuclear physics today. This study assesses the merits and significance of the science that could be addressed by an EIC, and its importance to nuclear physics in particular and to the physical sciences in general. It evaluates the significance of the science that would be enabled by the construction of an EIC, its benefits to U.S. leadership in nuclear physics, and the benefits to other fields of science of a U.S.-based EIC.

Available in PDF, EPUB and Kindle. Book excerpt: Electron Scattering from Complex Nuclei, Part B is a three-chapter text that explores the excitation of the nucleus to bound levels and the nucleus breakup through particle emission from continuum states. The first chapter discusses the inelastic scattering to nuclear levels, the giant resonances, the concepts of radiative corrections, and the phase shift analysis for inelastic scattering. The subsequent chapter concerns the quasi-elastic continuum and the observations of the nuclear decay products. The last chapter presents special topics on electron scattering, such as dispersion and exchange corrections, sum rules, and isospin effects. Physicists, researchers, and graduate students will find this book invaluable.
