Book excerpt: In conjunction with a vector polarization transfer measurement in the vector pp .-->. vector d.pi. reaction, we also obtained data on polarization observables for vector pp .-->. vector p.pi.n at 800 MeV incident proton energy. Scattered protons were detected in a spectrometer at angles from 5° to 11°. Pions were detected in coincidence at angles 80° to 130°. The proton momentum range covered was from 800 to 1300 MeV/c. The prominent peak observed near 1150 MeV/c in the proton spectrum is a reflection of .delta./sup + +/ production at center of mass angles from 0° to 30°. Regions of the spectrum corresponding to .delta./sup + +/ production at backward THETA/sub cm/ angles and to the 1S0 np final state interaction fall below the momentum acceptance limit for the spectrometer setting used in the present measurements. The events were binned into five proton momentum bins for the determination of the polarization observables D/sub NN/, P, and A.

Available in PDF, EPUB and Kindle. Book excerpt: For the first time the simultaneous separation of many RFs with a recoil polarization technique has been applied for measurements covering a large fraction of the phase space, even if for a single Q{sup 2}, W setting. The technique has been proven valid and 14 RFs can be individually extracted within the same set of measurements with the additional information coming from two combinations of the other 4. Then, the technical aim has been already achieved. Multipole decomposition, the most model independent analysis that can be made, is still to be done. Its result should give the physical information about the size of the small resonant and non resonant contributions. This is the physics aim of the experiment and will define the sensitivity of the technique. From this result one will infer the suitability to perform measurements at other Q{sup 2}, W settings or/and for other reactions. The technique is applicable to leptoproduction experiments in higher energy regimes provided that models, supposed to describe hadronic systems in that regimes, offer the opportunity to test their predictions in terms of RFs.

Download or read book Complete Atlas of Polarization Observables in Deuteron Photodisintegration Below Pion Threshold written by K.-M. Schmitt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time, a complete calculation of all 288 polarization observables of deuteron photodisintegration for polarized photons and an oriented deuteron target is presented for energies below +-production threshold. The observables are calculated within a nonrelativistic framework but with inclusion of lowest-order relativistic effects. Explicit meson exchange currents and isobar configurations as manifestation of subnuclear degrees of freedom are included in the calculation. The sensitivity of the various polarization observables with respect to subnuclear degrees of freedom, to electric and magnetic multipole contributions and to a variety of realistic potential models are systematically investigated. Thus this atlas provides the most detailed and systematic survey on polarization observables of this important process. It allows to analyse the different dynamical properties of the np-system as contained in the various observables and, therefore, will be useful for both theoretical studies and for the planning and evaluation of experiments as well. It serves in addition as an important supplement to the recent general review on deuteron photodisintegration by A. Arenhövel and M. Sanzone (Few-Body Systems, Suppl. 3).

This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the "International Conference on Spin Observables of Nuclear Probes" are presented in this volume. This conference was held in Telluride, Colorado, March 14-17, 1988, and was the fourth in the Telluride series of nuclear physics conferences. A continuing theme in the Telluride conference series has been the complementarity of various intermediate-energy projectiles for elucidating the nucleon-nucleon interaction and nuclear structure. Earlier conferences have contributed significantly to an understanding of spin currents in nuclei, in particular the distribution of Gamow-Teller strength using charge-exchange reactions. The previous conference on "Antinucleon and Nucleon Nucleus Interactions" compared nuclear information from tra tional probes to recent results from antinucleon reactions. The 1988 conference on Spin Observables of Nuclear Probes, put special emphasis on spin observables and brought together experts using spin information to probe nuclear structure. Spin observables have provided very detailed information about nuclear structure and reactions. Since the 1985 Telluride conference we have seen data from new focal plane polarimeters at LAMPF, TRIUMF, IUCF and elsewhere. In addition, spin observables provide an important common ground between electron and hadron scattering physics. In the future we look forward to new facilities such as NTOF for polarized neutron measurements at Los Alamos and a vigorous spin program at CEBAF.

Toki and published by World Scientific. This book was released on 2002 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NEWS99 international symposium discusses symmetries in electroweak processes in nuclei. Many phenomena in nuclear and particle physics are related to symmetry. It is known that we are living in a left-handed world as far as the Weak interaction is concerned, but neutrino physics suggests that a right-handed world may also be relevant. Chiral symmetry and its breaking plays an essential role in generating hadron masses. Symmetries related to flavor in the strong interaction like isospin, SU(3) and so on are known to be violated although they play a crucial role for the understanding of phenomena in nuclear and particle physics. The treatment of tiny breaking is of particular importance. Weak and electromagnetic interactions are well established at the fundamental level and can be used to probe the structure of nuclei and hadrons. A wide variety of phenomena in nuclear and particle physics were discussed in NEWS99 with an emphasis on symmetry. Topics ranged from nuclear structure to neutrino properties,,covering highly phenomenological to fundamental fields.

Download or read book Polarization Phenomena In Physics Applications To Nuclear Reactions written by Makoto Tanifuji and published by World Scientific. This book was released on 2018-04-17 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book allows the reader to understand the fundamentals of polarization phenomena in a general spin system, showing the polarizations to be indispensable information source of spin-dependent interactions. Particularly, the book describes polarization phenomena in nuclear scattering and reactions in detail, and explains how they provide information concerning spin-dependent interactions between the related particles. The concepts of polarization observables are explained, explicitly in the scattering of protons, deuterons and 7Li nuclei. In looking at deuteron and 7Li scattering, interactions induced by the virtual excitation of projectiles are examined in detail. Resonance reactions are investigated, focusing attention on the polarization of observables, which suggests that polarization phenomena can be used to determine the spin parity of the resonance. It is noted that in few-nucleon systems, the discrepancy between the values of polarization observables based on theoretical models and the corresponding values obtained through experimental data, is an important problem to be solved in the future. Solving this problem should provide new knowledge concerning the nuclear forces between nucleons.The author has chosen open-access publishing for this book to allow any interested person to study this branch of nuclear physics.

Download or read book Nuclear Physics with Polarized Particles written by Hans Paetz gen. Schieck and published by Springer Science & Business Media. This book was released on 2011-11-02 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: The measurement of spin-polarization observables in reactions of nuclei and particles is of great utility and advantage when the effects of single-spin sub-states are to be investigated. Indeed, the unpolarized differential cross-section encompasses the averaging over the spin states of the particles, and thus loses details of the interaction process. This introductory text combines, in a single volume, course-based lecture notes on spin physics and on polarized-ion sources with the aim of providing a concise yet self-contained starting point for newcomers to the field, as well as for lecturers in search of suitable material for their courses and seminars. A significant part of the book is devoted to introducing the formal theory—a description of polarization and of nuclear reactions with polarized particles. The remainder of the text describes the physical basis of methods and devices necessary to perform experiments with polarized particles and to measure polarization and polarization effects in nuclear reactions. The book concludes with a brief review of modern applications in medicine and fusion energy research. For reasons of conciseness and of the pedagogical aims of this volume, examples are mainly taken from low-energy installations such as tandem Van de Graaff laboratories, although the emphasis of present research is shifting to medium- and high-energy nuclear physics. Consequently, this volume is restricted to describing non-relativistic processes and focuses on the energy range from astrophysical energies (a few keV) to tens of MeV. It is further restricted to polarimetry of hadronic particles.
