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 2010 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the underlying mechanisms involved in the interactions between nucleons is one of the fundamental problems in nuclear physics. Over roughly the last 70 years, this question has been approached on many different fronts. We believe that the theory underlying the interaction between nucleons is that between quarks and gluons described by Quantum Chromodynamics; however, a complete solution to the nucleon-nucleon interaction within this framework has yet to emerge. In parallel, the advent of polarization experiments involving both polarized beams and targets has provided new experimental avenues to test our understanding the reaction mechanisms involved in the nucleon-nucleon interaction. One important example is the electrodisintegration of the deuteron ... (e[over-arrow], e'p)n, in particular the measurement of the beam-vector asymmetry, AV, and the tensor asymmetry, AT. Both of these asymmetries are sensitive to the d-wave components of the deuteron and are thus measurements of the effects of the tensor force in the nucleon-nucleon interaction. This work reports on measurements of AV and A T in the electrodisintegration of the deuteron that were performed by the BLAST collaboration at the Bates Linear Accelerator Center involving two data runs during 2004 and 2005. The measurements consisted of cross sections and asymmetries vs. missing momentum for a Q2 range of 0.1(GeV/c) 2

Book excerpt: We establish a simple, explicit relation between the formalisms employed in the treatments of polarization observables in deuteron two-body electrodisintegration published by Arenhovel, Leidemann, and Tomusiak in Few-Body Systems 15, 109 (1993) and the results of the present authors published in Phys. Rev. C 40, 2479 (1989). We comment on the overlap between the two sets of results.

Available in PDF, EPUB and Kindle. Book excerpt: We performed high precision measurements of induced and transferred recoil proton polarization in d($\vec{{u03B3}}$, $\vec{p}$)n for photon energies of 277--357 MeV and [theta]cm = 20 ° -- 120 °. The measurements were motivated by a longstanding discrepancy between meson-baryon model calculations and data at higher energies. Moreover, at the low energies of this experiment, theory continues to fail to reproduce the data, indicating that either something is missing in the calculations and/or there is a problem with the accuracy of the nucleon-nucleon potential being used.

This book was released on 1993-04-27 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop on Electronuclear Physics with Internal Targets brought together many experimentalists and theories in the field of electronuclear physics to discuss the next generation of experiments in this area. In line with the forward-looking theme of the workshop, the discussions centred on the many exciting new opportunities using polarized targets and the coincidental detection of electrons, pions and nucleons. With the upgrade to the MIT/Bates laboratory almost completed and the proposal for a large acceptance detector (BLAST) under review, these discussions can be said to be timely and appropriate.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the invited talks and contributed papers presented at the workshop on OC Testing QCD Through Spin Observables in Nuclear TargetsOCO, held at the University of Virginia in April 2002.The workshop was proposed in the context of the large number of experiments that have used polarized deuterons or polarized 3 He to extract information about the spin parameters of the neutron. The motivation for this workshop was to study the effects of the nuclear medium on the spin properties of the bound nucleon and to explore issues in QCD that might be resolved through spin observables in nuclear targets: What is the effect of the nuclear medium on the measured asymmetries? How have the latest results on the spin structure of the nucleon and the nucleon form factors changed our thinking? What advances are anticipated in the development of polarized targets?"

Available in PDF, EPUB and Kindle. Book excerpt: More than 50 years ago, in 1934, Chadwick and Goldhaber (ChG 34) published a paper entitled "A 'Nuclear Photo-effect': Disintegration of the Diplon by -y-Rays."l in the introduction: They noted "By analogy with the excitation and ionisation of atoms by light, one might expect that any complex nucleus should be excited or 'ionised', that is, disintegrated, by -y-rays of suitable energy", and furthermore: "Heavy hydrogen was chosen as the element first to be examined, because the diplon has a small mass defect and also because it is the simplest of all nuclear systems and its properties are as important in nuclear theory as the hydrogen is in atomic theory". Almost at the same time, in 1935, the first theoretical paper on the photodisinte gration of the deuteron entitled "Quantum theory of the diplon" by Bethe and Peierls (BeP 35) appeared. It is not without significance that these two papers mark the be ginning of photonuclear physics in general and emphasize in particular the special role the two-body system has played in nuclear physics since then and still plays. A steady flow of experimental and theoretical papers on deuteron photo disintegration and its inverse reaction, n-p capture, shows the continuing interest in this fundamental process (see fig. 1.1).

This book was released on 1995-02-17 with total page 882 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main goals of intermediate energy nuclear physics, which serves an important role as a bridge between nuclear and particle physics, is to construct the theory of strong interaction phenomena in terms of conventional degrees of freedom (nucleons, deltas and mesons) as well as of quark degrees of freedom.The main topics to be discussed at this conference are the interaction of pions and other mesons with nuclei at intermediate energies and the role of mesonic degrees of freedom in nuclear reactions, including photon, hadron and heavy ion induced reactions. Both theoretical and experimental results will be included.Over the past two decades, the Meson Factories, including LAMPF, TRIUMF, and PSI, have provided us with systematic experimental information on hadron-hadron and hadron-nucleus dynamics. Major accelerators of JINR are also suitable for studying problems in Intermediate Energy Nuclear Physics. At the present time, first experiments have been performed with the proton beams at the Moscow Meson Factory of INR. One of the purposes of this conference is to introduce the intermediate-energy physics community to the possibility of utilizing the facilities of JINR and INR during the next decade.
