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.

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.

Download or read book The Connectivity Hypothesis written by Ervin Laszlo and published by State University of New York Press. This book was released on 2010-03-10 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ervin Laszlo, widely regarded as the founder of systems philosophy and general evolution theory, introduces the foundations of a genuine unified theory of the world in this pioneering treatise on the new sciences. In contrast to other unified theories that center mainly on physics, Laszlo's embraces quantum, cosmos, life, as well as consciousness. He delineates the principles of a new physics of universal connectivity and puts forth the corresponding metaphysics, discussing the implications for such philosophical issues as the nature of matter and mind, freedom and morality, and design versus evolution. This landmark book lays the groundwork for the non-materialist and non-reductionist yet rigorous paradigm that is likely to signal the next revolution in science: the "paradigm of universal connectivity."

Download or read book Positron and Positronium Chemistry written by D. M. Schrader and published by Elsevier Publishing Company. This book was released on 1988 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the use and significance of positrons in several fields of chemistry, including chemical analysis, surface chemistry, quantum chemistry, the structure of molecular solids, radiation chemistry, the structures of supramolecular species (polymers, vesicles, micelles, etc.), clustering phenomena in gases, etc. Because the positron is an unfamiliar particle to most chemists, the first chapter provides an easily understood introduction to this fascinating chemical species. Applications of various positron techniques to practical problems in chemistry are described which will be interesting and useful to many chemists. Some will find new methods of enquiry into their own systems, and new ways of thinking about them. Practical details of how to set up experiments are given, and information about what can be learned from the data is provided. This is the first comprehensive treatment of the subject in almost 25 years. It will be of interest to those in all fields of chemistry as well as certain areas of biology and materials science. The book features an excellent subject index and a full authors' index and is illustrated by 139 graphs and drawings.

Download or read book Theory of Quadsitron Energy Connectivity written by Lane B. Scheiber, Ii. MD. and published by . This book was released on 2019-05-23 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The luminous aether, a concept known for hundreds of years, is the fine essence of the universe. Over the last 130 years, mainstream science abandoned the knowledge such an aether existed. Yet, reawakening the principles of a luminous aether as the fabric of space--both within our being and surrounding us, reaching out in every direction to the very edges of the universe-- explains many unsolved mysteries. The luminous aether is a vast three-dimensional ocean of the tiniest and most elemental particles called quadsitrons. From the fusion of quadsitrons and energy, all else in the universe is constructed. The dynamics of quadsitrons interacting with energy accounts for and connects all the micro and macrophenomena that fill our lives, such as gravity, light, electrons, atoms, molecules, and magnetism. It is essential we understand and grasp the principles of this wondrous quadsitron-energy connectivity in order to advance our technology forward to interstellar travel.

Available in PDF, EPUB and Kindle. Book excerpt: The interplay between atomic and nuclear interactions in heavy ion collisions with nuclear contact is studied. The general theoretical description is outlined and analyzed in a number of different limits (semiclassical approximation, DWBA, fully quantal description). The two most important physical mechanisms for generating atomic-nuclear interference, i.e., energy conservation and the introduction of additional phase shifts by nuclear reactions, are extracted. The resulting typical coupling matrix elements are analyzed for their relative importance in atomic and nuclear excitations. The description of nuclear influence on atomic excitations in terms of a classical time delay caused by nuclear reactions is reviewed, and its relationship to the underlying quantal character of the nuclear reaction is discussed. The theory is applied to spontaneous positron emission in supercritical heavy-ion collisions (Z/sub tot/ greater than or equal to 173). It is shown that nuclear contact can lead to line structures in the positron energy spectra if the probability distribution for nuclear delay times caused by the contact has contributions for T greater than or equal to 10−19 sec. We explicitly evaluate a model where a pocket in the internuclear potential near the touching configuration leads to formation of nuclear molecules, and predict a resonance-like excitation function for the positron peak. 25 refs., 7 figs.
