Available in PDF, EPUB and Kindle. Book excerpt: The analysis of the data from the MIT-Bates experiment in June 1993 to measure the helicity-dependent asymmetry in quasielastic scattering of polarized electrons from polarized 3He was completed. The neutron magnetic form factor was extracted from data on polarized 3He for the first time and is found to be in very good agreement with the dipole form at Q2 = 0. 19 (GeV/c)2. A paper reporting the transverse asymmetry and the extracted value of the neutron magnetic form factor was published, and papers reporting the transverse-longitudinal asymmetries at the quasielastic peak and on the low energy-transfer side of the quasielastic peak were submitted for publication.

Download or read book Measurement of the Target normal Single spin Asymmetry in Quasielastic Scattering from the Reaction math Display written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the first measurement of the target single-spin asymmetry, Ay, in quasi-elastic scattering from the inclusive reaction 3He1!(e, e') on a 3He gas target polarized normal to the lepton scattering plane. Assuming time-reversal invariance, this asymmetry is strictly zero for one-photon exchange. A non-zero Ay can arise from the interference between the one- and two-photon exchange processes which is sensitive to the details of the sub-structure of the nucleon. An experiment recently completed at Jefferson Lab yielded asymmetries with high statistical precision at Q2= 0.13, 0.46 and 0.97 GeV2. These measurements demonstrate, for the first time, that the 3He asymmetry is clearly non-zero and negative with a statistical significance of (8-10)[sigma]. Using measured proton-to-3He cross-section ratios and the effective polarization approximation, neutron asymmetries of -(1-3)% were obtained. The neutron asymmetry at high Q2 is related to moments of the Generalized Parton Distributions (GPDs). Our measured neutron asymmetry at Q2=0.97 GeV2 agrees well with a prediction based on two-photon exchange using a GPD model and in addition provides a new independent constraint on these distributions.

Available in PDF, EPUB and Kindle. Book excerpt: Optics of Charged Particles, 2nd edition, describes how charged particles move in the fields of magnetic and electrostatic dipoles, quadrupoles, higher order multipoles, and field-free regions. Since the first edition, published over 30 years ago, new technologies have emerged and have been used for new ion optical instruments like, for instance, time-of-flight mass analyzers, which are described now. Fully updated and revised, this new edition provides ways to design mass separators, spectrographs, and spectrometers, which are the key tools in organic chemistry and for drug developments, in environmental trace analyses and for investigations in nuclear physics like the search for super heavy elements as well as molecules in space science. The book discusses individual particle trajectories as well as particle beams in space and in phase-space, and it provides guidelines for the design of particle optical instruments. For experienced researchers, working in the field, it highlights the latest developments in new ion optical instruments and provides guidelines and examples for the design of new instruments for the transport of beams of charged particles and the mass/charge or energy/charge analyses of ions. Furthermore, it provides background knowledge required to accurately understand and analyze results, when developing ion-optical instruments. By providing a comprehensive overview of the field of charged particle optics, this edition of the book supports all those working, directly or indirectly, with charged-particle research or the development of ion- and electron-analyzing instruments. Provides enhanced, clear descriptions, and derivations making complex aspects of the general motion of charged particles understandable as well as features of charged particle analyzing instruments Assists the reader in applying insights obtained from the principles of charged particle optics to the design of new transporting and mass- or energy-analyzing instruments for ions Discusses new applications and newly occurring issues, which have arisen since the first edition

Download or read book Fractal Space time and Microphysics written by Laurent Nottale and published by World Scientific. This book was released on 1993 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first detailed account of a new approach to microphysics based on two leading ideas: (i) the explicit dependence of physical laws on scale encountered in quantum physics, is the manifestation of a fundamental principle of nature, scale relativity. This generalizes Einstein's principle of (motion) relativity to scale transformations; (ii) the mathematical achievement of this principle needs the introduction of a nondifferentiable space-time varying with resolution, i.e. characterized by its fractal properties.The author discusses in detail reactualization of the principle of relativity and its application to scale transformations, physical laws which are explicitly scale dependent, and fractals as a new geometric description of space-time.

Download or read book The Nucleon Optical Model written by Peter Edward Hodgson and published by World Scientific. This book was released on 1994 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nucleon optical model is widely used to calculate the elastic scattering cross-sections and polarisations for the interaction of neutrons and protons with atomic nuclei. The optical model potentials not only describe the scattering but also provide the wave functions needed to analyse a wide range of nuclear reactions. They also unify many aspects of nuclear reactions and nuclear structure. This book consists of a comprehensive introduction to the subject and a selection of papers by the author describing the optical model in detail. It contains full references to the original literature with many examples of the application of the model to the analysis of experimental data.

This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based mostly on the reports presented at the XVth International lahn-Teller Symposium on Vibronic Interactions in Crystals and Molecules and NATO Advanced Research Workshop Colossal Magnetoresistance and Vibronic Interactions that took place at Boston on August 16-22 of the year 2000. This is the first time the Symposium took place in the USA where recently the giant splash of the attention to the 1 ahn-Teller effect occurred. This tremendous interest to the field all over the world is reflected not only in the numerous publications in many American and European 10urnals, but of the leading scientists from additionally in the Symposium's participation the well known Universities, National Laboratories and industrial companies, which was the largest in the history of the Symposium. The renaissance of the 1ahn-Teller physics is closely related to the three fundamental discoveries in science. The most significant among them is the discovery of high-Tc superconductivity by K. -A. Muller and G. Bednorz, for whom the "1ahn-Teller idea" was the motivation in their search. The result of this search is well known - a wide spectrum of the 1ahn-Teller ion based materials with Tc between 24K and 135K were found. The second discovery is the existence of a new polymorph of carbon - the C60. The microscopic analysis of all physical, chemical and biological properties of the buckyballs is based on 1ahn-Teller type of interactions. The third is colossal magnetoresistance.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the classroom, the most important meeting place for teachers and pupils in an education building. Our knowledge, however, about what happens inside this space is limited. In many respects the classroom is still the black box of the educational system. To open up this box, this volume brings together scholars from the disciplines of Art, Architecture, History, Pedagogy and Sociology. They present a wide variety of new perspectives, methodologies and sources for studying classrooms. The book examines images and representations of classrooms (photographs, paintings and pictures on school walls), writings and documents inside the classroom (school exercise books, teachers' log books and observer reports), memories and personal experiences of classrooms (egodocuments from teachers and pupils, and oral history interviews), the space and design of classrooms (architecture, school murals and the transformation of space), and material objects in the classroom (school furniture, primers for reading and school wall charts). The essays are illustrated with a unique collection of more than fifty photographs of classrooms in Europe.
Download or read book Inside the Black Box of Classroom Practice written by Larry Cuban and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inside the Black Box of Classroom Practice takes as its starting point a strikingly blunt question: "With so many major structural changes in U.S. public schools over the past century, why have classroom practices been largely stable, with a modest blending of new and old teaching practices, leaving contemporary classroom lessons familiar to earlier generations of school-goers?" It is a question that ought to be of paramount interest to all who are interested in school reform in the United States. It is also a question that comes naturally to Larry Cuban, whose much-admired books have focused on various aspects of school reform--their promises, wrong turns, partial successes, and troubling failures. In this book, he returns to this territory, but trains his focus on the still baffling fact that policy reforms--no matter how ambitious or determined--have generally had little effect on classroom conduct and practice. "For forty years, Larry Cuban has been a voice of thoughtful analysis amid the overwrought rhetoric of American education reform. His distinctive contribution--updated, deepened, and extended in this book--has been to focus our attention on the persistent gap between the misconceptions of policy elites and the realities of daily practice in the classroom. One hopes that the next generation of American educators will learn the essential lessons of Cuban's analysis more deeply than the current generation. Young people considering a career in education should hold the lessons of this book close to their hearts." -- Richard F. Elmore, Gregory R. Anrig Professor of Educational Leadership, Harvard Graduate School of Education "Larry Cuban's well-written book convincingly demonstrates why current education reforms don't work, can't work, and won't work." -- Diane Ravitch, research professor of education, New York University "Anyone with a deep interest in public schools should read Inside the Black Box of Classroom Practice. Cuban takes the reader through the history of earnest efforts to improve our schools--through technology, structural reforms, and accountability systems--and shows why they have met with mixed and often disappointing results. His recommendations for us are both cautionary and hopeful, and always respectful of the dilemmas that teachers face each day they walk through the classroom door." -- Gary Yee, board director, District Four, Oakland Unified School District, and retired vice chancellor, Educational Services, Peralta Community College District Larry Cuban is professor emeritus of education at Stanford University.
