Book Synopsis Positrons in Solids by : P. Hautojärvi
Download or read book Positrons in Solids written by P. Hautojärvi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In condensed matter initially fast positrons annihilate after having reached equi librium with the surroundings. The interaction of positrons with matter is governed by the laws of ordinary quantum mechanics. Field theory and antiparticle properties enter only in the annihilation process leading to the emergence of energetic photons. The monitoring of annihilation radiation by nuclear spectroscopic methods provides valuable information on the electron-positron system which can directly be related to the electronic structure of the medium. Since the positron is a positive electron its behavior in matter is especially interesting to solid-state and atomic physi cists. The small mass quarantees that the positron is really a quantum mechanical particle and completely different from any other particles and atoms. Positron physics started about 25 years ago but discoveries of new features in its interac tion with matter have maintained continuous interest and increasing activity in the field. Nowadays it is becoming part of the "stock-in-trade" of experimental physics.

Book Synopsis Physics with Many Positrons by : Alfredo Dupasquier
Download or read book Physics with Many Positrons written by Alfredo Dupasquier and published by IOS Press. This book was released on 2010 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the exception of positron emission tomography (PET), the field of low energy positron science produces relatively few academic articles each year compared to more accessible fields. Though much has been achieved since the publication of two related volumes earlier in this series: Positron Solid State Physics (1981) and Positron Spectroscopy of Solids (1993), only the first steps have been made towards 'physics with many positrons': physical situations where the interactions of positrons with positrons can be observed. This 2009 "Enrico Fermi School" aims to stimulate the field o.
Book Synopsis Atomic Physics with Positrons by : J.W. Humberston
Download or read book Atomic Physics with Positrons written by J.W. Humberston and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Research Workshop on Atomic Physics with Positrons, which was held at University College London during 15-18 July 1987, was the fourth meeting in a series devoted to the general theme of positron colli sions in gases. Previous meetings have been held at York University, Toronto (1981); Royal Holloway College, Egham (1983) and Wayne State Uni versity, Detroit (1985). Recent very significant improvements in positron beam currents, due to the development of more efficient moderators and the use of more intense positron sources, are making possible an increasingly sophisticated range of experiments in atomic collision physics. Whereas a few years ago only total scattering cross sections could be determined, measurements can now be made of various partial and differential cross sections. Intense positron beams are also being used to produce positronium beams and already, as reported here, preliminary investigations have been made of collisions of positronium with several target systems. These experimental developments have stimulated, and been stimulated by, steady, if somewhat less spectacu1ar,progress in associated theoretical studies. Both aspects of the field are well represented in these Proceed ings.
Book Synopsis High Energy Electron-positron Physics by : Ahmed Ali
Download or read book High Energy Electron-positron Physics written by Ahmed Ali and published by World Scientific. This book was released on 1988 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the termination of the physics program at PETRA, and with the start of TRISTAN and the SLC and later LEP, an era of e+e- physics has come to an end and a new one begins. The field is changing from a field of few specialists, to becoming one of the mainstream efforts of the high energy community. It seems appropriate at this moment to summarize what has been learned over the past years, in a way most useful to any high energy physicists, in particular to newcomers in the e+e- field. This is the purpose of the book. This book should be used as a reference for future workers in the field of e+e- interactions. It includes the most relevant data, parametrizations, theoretical background, and a chapter on detectors.

Book Synopsis Electron-Positron Physics at the Z by : M. G. Green
Download or read book Electron-Positron Physics at the Z written by M. G. Green and published by CRC Press. This book was released on 1998 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive summary of studies of the Z boson in electron positron interactions. The results that have been obtained have achieved unprecedented accuracy and have firmly established the Electroweak Standard Model as the cornerstone of our current understanding of modern particle physics. The book introduces the background to the Standard Model and the role of the Z boson and describes briefly the accelerators and experiments involved in these results. The five main chapters deal with the detailed measurements of the electroweak parameters of the Z, the study of QCD, heavy quark physics, tau lepton physics and the search for new particles. Each chapter ends with a summary and outlook to prospects of future accelerators. Most of the results are from the first six years running at the first phase of electron positron collider, LEP, at energies corresponding to the Z mass, but results from the SLAC Linear Collider and some new results at higher energies are also included.

Book Synopsis Positron Spectroscopy of Solids by : Società italiana di fisica
Download or read book Positron Spectroscopy of Solids written by Società italiana di fisica and published by IOS Press. This book was released on 1995 with total page 807 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lifetime of a positron inside a solid is normally less than a fraction of nanosecond. This is a very short time on a human scale, but is long enough to enable the positron to visit an extended region of the material, and to sense the atomic and electronic structure of the environment. Thus, we can inject a positron in a sample to draw from it some signal giving us information on the microscopic properties of the material. This idea has been successfully developed in a number of positron-based techniques of physical analysis, with resolution in energy, momentum, or position. The complex of these techniques is what we call now positron spectroscopy of solids. The field of application of the positron spectroscopy extends from advanced problems of solid-state physics to industrial applications in the area of characterization of high-tech materials. This volume focuses the attention on the physics that can be learned from positron-based methods, but also frames those methods in a wider context including other experimental approaches. It can be considered as a textbook on positron spectroscopy of solids, the sort of book that the newcomer takes for his approach to this field, but also as a useful research tool for the expert.

Book Synopsis New Directions in Antimatter Chemistry and Physics by : Clifford M. Surko
Download or read book New Directions in Antimatter Chemistry and Physics written by Clifford M. Surko and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the outgrowth of a workshop held in October, 2000 at the Institute for Theoretical Atomic and Molecular Physics at the Harvard- Smithsonian Center for Astrophysics in Cambridge, MA. The aim of this book (similar in theme to the workshop) is to present an overview of new directions in antimatter physics and chemistry research. The emphasis is on positron and positronium interactions both with themselves and with ordinary matter. The timeliness of this subject comes from several considerations. New concepts for intense positron sources and the development of positron accumulators and trap-based positron beams provide qualitatively new experimental capabilities. On the theoretical side, the ability to model complex systems and complex processes has increased dramatically in recent years, due in part to progress in computational physics. There are presently an intriguing variety of phenomena that await theoretical explanation. It is virtually assured that the new experimental capabilities in this area will lead to a rapid expansion of this list. This book is organized into four sections: The first section discusses potential new experimental capabilities and the uses and the progress that might be made with them. The second section discusses topics involving antihydrogen and many-body phenomena, including Bose condensation of positronium atoms and positron interactions with materials. The final two sections treat a range of topics involving positron and positronium interactions with atoms and molecules.

Download or read book The Positron written by Paul F. Kisak and published by Createspace Independent Publishing Platform. This book was released on 2016-01-24 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1 e, a spin of 1/2, and has the same mass as an electron. When a low-energy positron collides with a low-energy electron, annihilation occurs, resulting in the production of two or more gamma ray photons. Positrons may be generated by positron emission radioactive decay (through weak interactions), or by pair production from a sufficiently energetic photon which is interacting with an atom in a material. In 1928, Paul Dirac published a paper[2] proposing that electrons can have both a positive charge and negative energy. This paper introduced the Dirac equation, a unification of quantum mechanics, special relativity, and the then-new concept of electron spin to explain the Zeeman effect. This book discusses the positron and it's latest uses in technology.

Book Synopsis Positron Profilometry by : Jerzy Dryzek
Download or read book Positron Profilometry written by Jerzy Dryzek and published by Springer Nature. This book was released on 2023-09-08 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of positron profilometry, specifically focusing on the analysis of defect depth distribution in materials. Positron profilometry plays a crucial role in understanding and characterizing defects in a wide range of materials, including metals, semiconductors, polymers, and ceramics. By analyzing the depth distribution of defects, researchers can gain insights into various material properties, such as crystal structure, defect density, and diffusion behavior. The author's extensive research spanning a period of two decades has primarily centered on subsurface zones. These regions, located beneath the surface and subjected to various surface processes, play a crucial role in generating defect distributions. Three experimental techniques and their data analysis are described in detail: a variable-energy positron beam (VEP) called sometimes a slow positron beam, a technique called implantation profile depth scanning (DSIP), and a sequential etching (SET) technique. The usability of these techniques is illustrated by many examples of measurements by the author and others.
