Available in PDF, EPUB and Kindle. Book excerpt: Because it determines many of the features of nuclear reactions, such as knockout, inelastic scattering, and transfer processes at high energies, the momentum distribution of the nucleons in atomic nuclei is crucial to our understanding of nuclear structure. The distribution can be calculated from several models and the correctness of the result assessed experimentally. Due to the effects of short-range correlations and the many-body nature of the problem, these calculations are often difficult, requiring a variety of mathematical techniques. This book discusses these techniques and shows how the results may be related to measurements in the lab. This is a complete sourcebook for theoretical and experimental nuclear physicists.

Download or read book Nucleon Correlations in Nuclei written by Anton N. Antonov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been growing interest in the nucleon-nucleon correl ations inside nuclei. In many respects the motions of the nucleons can be very well described by an overall mean field, so that the motion of each nucleon is governed by the mean field due to all the other nucleons. This concept underlies the Fermi-gas, Hartree-Fock and shell models and has enabled a range of nuclear properties to be calculated, often to surprising accuracy. It gradually became clear, however, that these mean-field models are limited by the effects due to the very strong interactions between the nucleons that occur at short distances; these are the short-range correlations. They are responsible for instance for the high-momentum components in the nucleon momentum dis tribution, and prevent the simultaneous description of the nuclear density and momentum distributions by the same mean field. It thus becomes necessary to develop methods for including the effects of nucleon correlations in nuclei, and these are the main subject of this book. Some related problems of nuclear structure were discussed in an earlier book by the same authors: Nucleon Momentum and Density Distributions in Nuclei (Clarendon Press, Oxford, 1988). The main aim of that book was to study the effects of nucleon-nucleon correlations, both short-range and tensor, on the nucleon momentum distribution, which is particularly sensitive to these correl ations, and on the nucleon density distribution.

Book Synopsis Momentum Distributions by : Richard N. Silver
Download or read book Momentum Distributions written by Richard N. Silver and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the proceedings of the Workshop on Momentum Distributions held on October 24 to 26, 1988 at Argonne National Laboratory. This workshop was motivated by the enormous progress within the past few years in both experimental and theoretical studies of momentum distributions, by the growing recognition of the importance of momentum distributions to the characterization of quantum many-body systems, and especially by the realization that momentum distribution studies have much in common across the entire range of modern physics. Accordingly, the workshop was unique in that it brought together researchers in nuclear physics, electronic systems, quantum fluids and solids, and particle physics to address the common elements of momentum distribution studies. The topics dis cussed in the workshop spanned more than ten orders of magnitude range in charac teristic energy scales. The workshop included an extraordinary variety of interactions from Coulombic to hard core repulsive, from non-relativistic to extreme relativistic.
Book Synopsis Nucleon and Nucleon-pair Momentum Distributions in Ad"2 Nuclei by :
Download or read book Nucleon and Nucleon-pair Momentum Distributions in Ad"2 Nuclei written by and published by . This book was released on 2014 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report variational Monte Carlo calculations of single-nucleon momentum distributions for Ad"2 nuclei and nucleon-pair and nucleon-cluster momentum distributions for Ad". The wave functions have been generated for a Hamiltonian containing the Argonne [nu]18 two-nucleon and Urbana X three-nucleon potentials. The single-nucleon and nucleon-pair momentum distributions exhibit universal features attributable to the one-pion-exchange tensor interaction The single-nucleon distributions are broken down into proton and neutron components and spin-up and spin-down components where appropriate. The nucleon-pair momentum distributions are given separately for pp and pn pairs. The nucleon-cluster momentum distributions include dp in 3He, tp and dd in S4He, [alpha]d in 6Li, [alpha]t in 7Li, and [alpha][alpha] in 8Be. Detailed tables are provided on-line for download.

Book Synopsis A Study of Nuclear Momentum Distributions and Elastic Form Factors by : Marwan Hasan
Download or read book A Study of Nuclear Momentum Distributions and Elastic Form Factors written by Marwan Hasan and published by LAP Lambert Academic Publishing. This book was released on 2012-07 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work is to discuss the utility of electron scattering in the study of nuclear properties. The Nucleon Momentum Distributions (NMD) and elastic electron scattering form factors of the ground state for 1p-shell nuclei have been calculated in the framework of the Coherent Density Fluctuation Model (CDFM) and expressed in terms of the weight function. The feature of the long-tail behavior at high momentum region of the NMD has been obtained by both the theoretical and experimental weight functions on contrary to the results of the NMD calculated in the shell model by taking Fourier transform to the harmonic oscillator wave functions that are mainly characterized by the steep slope behavior at high momentum values. The experimental form factors of all considered nuclei are very well reproduced by the present calculations throughout all values of momentum transfer q. It is found that the contributions of the quadrupole form factors, which are described by the undeformed p-shell model, are essential in obtaining a remarkable agreement between the theoretical and experimental form factors.

This book was released on 2020-05-29 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains proceedings of the 7-week INT program dedicated to the physics of the Electron-Ion Collider (EIC), the world's first polarized electron-nucleon (ep) and electron-nucleus (eA) collider to be constructed in the United States. The 2015 NSAC Long Range Plan recommended EIC as the 'highest priority for new facility construction following the completion of FRIB'. The primary goal of the EIC is to establish precise multi-dimensional imaging of quarks and gluons inside nucleons and nuclei. This includes (i) understanding the spatial and momentum space structure of the nucleon through the studies of TMDs (transverse-momentum-dependent parton distributions), GPD (generalized parton distributions) and the Wigner distribution; (ii) determining the partonic origin of the nucleon spin; (iii) exploring the new quantum chromodynamics (QCD) frontier of ultra-strong gluon fields, with the potential to seal the discovery of a new form of dense gluon matter predicted to exist in all nuclei and nucleons at small Bjorken x — the parton saturation.The program brought together both theorists and experimentalists from Jefferson Lab (JLab), Brookhaven National Laboratory (BNL) along with the national and international nuclear physics communities to assess and advance the EIC physics.
Book Synopsis Dependence of Two-nucleon Momentum Densities on Total Pair Momentum by :
Download or read book Dependence of Two-nucleon Momentum Densities on Total Pair Momentum written by and published by . This book was released on 2008 with total page 21001 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-nucleon momentum distributions are calculated for the ground states of 3He and 4He as a function of the nucleons' relative and total momenta. We use variational Monte Carlo wave functions derived from a realistic Hamiltonian with two- and three-nucleon potentials. The momentum distribution of pp pairs is found to be much smaller than that of pn pairs for values of the relative momentum in the range (300--500) MeV/c and vanishing total momentum. However, as the total momentum increases to 400 MeV/c, the ratio of pp to pn pairs in this relative momentum range grows and approaches the limit 1/2 for 3He and 1/4 for 4He, corresponding to the ratio of pp to pn pairs in these nuclei. This behavior should be easily observable in two-nucleon knock-out processes, such as A(e, e'pN). http://dx.doi.org/10.1103/PhysRevC.78.021001.

Available in PDF, EPUB and Kindle. Book excerpt: Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.
Book Synopsis From Nucleons to the Atomic Nucleus by : Kris Heyde
Download or read book From Nucleons to the Atomic Nucleus written by Kris Heyde and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present text grew out of a number of lecture courses for advanced under graduate and new graduate students in nuclear physics. They were given at summer schools in Leuven, Melbourne, and at study weeks for Dutch grad uate students which aimed to emphasize fundamental and topical aspects of nuclear physics. On occasion, part of the present text was presented to stu dents from a much wider field than just nuclear physics and also within a number of general physics colloquia, where, in addition to nuclear physicists, physicists from many other fields were present. In this respect, the intention is to present, in an amply illustrated form, the key quest ions that arise in nuclear physics. At the same time we try to show why a better understanding of the atomic nucleus is not only important in itself, but also yields essential insights into the many connections to other fields of physics. We thus concen trate on the unifying themes rather than addressing in great detail particular subfields of nuclear physics. The present project does not aim to be another comprehensive textbook on nuclear physics: Many of the detailed technical arguments that enter into the picture are not developed here as they would be in a more standard textbook. Instead they are presented using analogies, quite often with simple pictures and arguments that try to convey the general line of thinking and working in nuclear physics.
Book Synopsis Nucleon Momentum Distributions from a Modified Scaling Analysis of Inclusive Electron Nucleus Scattering by : John Arrington
Download or read book Nucleon Momentum Distributions from a Modified Scaling Analysis of Inclusive Electron Nucleus Scattering written by John Arrington and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Inclusive electron scattering from nuclei at low momentum transfer (corresponding to x>1) and moderate Q^2 is dominated by quasifree scattering from nucleons. In the impulse approximation, the cross section can be directly connected to the nucleon momentum distribution via the scaling function F(y). The breakdown of the y-scaling assumptions in certain kinematic regions have prevented extraction of nucleon momentum distributions from such a scaling analysis. With a slight modification to the y-scaling assumptions, it is found that scaling functions can be extracted which are consistent with the expectations for the nucleon momentum distributions.
