Book Introduction to Photoelectron Angular Distributions

Download or read book Introduction to Photoelectron Angular Distributions written by V. T. Davis and published by Springer Nature. This book was released on 2022-11-30 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to photoelectron angular distributions and their use in the laboratory to study light-matter interactions. Photoelectron angular distribution measurements are useful because they can shed light on atomic and molecular electronic configurations and system dynamics, as well as provide information about quantum transition amplitudes and relative phases that are not obtainable from other types of measurements. For example, recent measurements of molecular-frame photoelectron angular distributions have been used to extract photoelectron emission delays in the attosecond range which can provide ultra-sensitive maps of molecular potentials. Additionally, photoelectron angular distribution measurements are an essential tool for studying negative ions. Here, the author presents a detailed, yet easily accessible, theoretical background necessary for experimentalists performing photoelectron angular distribution measurements to better understand their results. The various physical influences on photoelectron angular distributions are revealed through analytical models with the use of angular momentum coupling algebra and spherical tensor operators. The classical and quantum treatments of photoelectron angular distributions are covered clearly and systematically, and the book includes, as well, a chapter on relativistic interactions. Furthermore, the primary methods used to measure photoelectron angular distributions in the laboratory, such as photodetachment electron spectroscopy, velocity-map imaging, and cold target recoil ion momentum spectroscopy, are described. This book features introductory material as well as new insights on the topic, such as the use of angular momentum transfer theory to understand the process of photoelectron detachment in atoms and molecules. Including key derivations, worked examples, and additional exercises for readers to try on their own, this book serves as both a critical guide for young researchers entering the field and as a useful reference for experienced practitioners.

Book Energy and Angular Distribution of Neutrons and Gamma Rays

Download or read book Energy and Angular Distribution of Neutrons and Gamma Rays written by J. H. Thorngate and published by . This book was released on 1969 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where possible, these data have been compared with data from previous field experiments. In every case, they were compared with calculations which approximated the experiment. Agreement in both cases is generally good, and this strengthens confidence in calculated results.

Book Dijet Angular Distributions in Proton Proton Collisions

Download or read book Dijet Angular Distributions in Proton Proton Collisions written by Nele Boelaert and published by Springer Science & Business Media. This book was released on 2011-10-26 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is based on the first data from the Large Hadron Collider (LHC) at CERN. Its theme can be described as the classical Rutherford scattering experiment adapted to the LHC: measurement of scattering angles to search for new physics and substructure. At the LHC, colliding quarks and gluons exit the proton collisions as collimated particle showers, or jets. The thesis presents studies of the scattering angles of these jets. It includes a phenomenological study at the LHC design energy of 14 TeV, where a model of so-called large extra dimensions is used as a benchmark process for the sensitivity to new physics. The experimental result is the first measurement, made in 2010, by ATLAS, operating at the LHC start-up energy of 7 TeV. The result is compatible with the Standard Model and demonstrates how well the physics and the apparatus are understood. The first data is a tiny fraction of what will be accumulated in the coming years, and this study has set the stage for performing these measurements with confidence as the LHC accumulates luminosity and increases its energy, thereby probing smaller length scales.

Book A Companion to Angular Momentum

Download or read book A Companion to Angular Momentum written by Valeria D. Kleiman and published by John Wiley & Sons. This book was released on 1998-09-30 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angular momentum is a basic concept used in classical physics. Examples of phenomena that are related to angular momentum are: 1) Why a moving bicycle does not fall over and 2) why the currents in the ocean of the rotating earth tend to follow circular motions. Designed as a learning tool for those with limited background in quantum mechanics and to compliment Zare's Angular Momentum, this book provides examples, problems, & solutions in angular momentum in quantum mechanics and its applications to chemistry and physics.
