Two-nucleon Short-range Correlations in Light Nuclei

Pages : 205
Book Description
Understanding the nucleon-nucleon (NN) interaction is a fundamental task in nuclear physics, as NN-interaction models are a crucial input to modern nuclear structure calculations. While great progress has been made toward understanding this interaction, the available state-of-the-art models predict significantly different behaviors at short distances and high momenta (scale-and-scheme dependence), where two-nucleon Short-Range Correlations (SRCs) dominate the nuclear wave function. Thus, SRCs are a unique tool to constrain the NN interaction and vice versa. SRCs are naturally-occurring high-local-density NN pairs that, as a result of their short-distance (r /~ 1 fm) repulsive interaction, fly apart with high momenta, hence populating momentum states above the Fermi level (k /~ & k[subscript F]~~ 250 MeV/c). The study of SRCs also has significant implications for other fields, such as the astrophysics of neutron stars and the behavior of cold atomic gasses. This thesis describes experimental and phenomenological studies of the short-distance / high-momentum structure of the NN interaction through the study of SRCs and vice versa. Experimentally, I report the first measurement of the 3He and 3H(e, e'p) reactions in Hall A of the Thomas Jefferson National Accelerator Facility in kinematics in which the measured cross sections should be sensitive to the underlying nucleon momentum distributions in the range 40 to 500 MeV/c. The resulting cross-section ratios and absolute cross sections were compared to momentum-distribution ratios and precise cross-section calculations respectively. Phenomenologically, I report the generalization of the Contact Formalism (GCF) to nuclear systems, which exploits scale separation and universality to describe nucleons at short distances and high momenta.

Few body dynamics
Author: Asoke Mitra
Publisher: Elsevier
ISBN: 0444601090
Category : Science
Languages : en
Pages : 792
Book Description
Few Body Dynamics presents the proceedings of the VII International Conference on Few Body Problems in Nuclear and Particle Physics, held in Delhi from December 29, 1975 to January 3, 1976. Invited speakers talked about topics ranging from dynamic equations and approximation methods to computation and experimental techniques, few body bound states, breakup reactions and polarization, few electron systems, and photon and electron probes on few body systems. Speakers also covered few body reactions with mesons and resonances, few body aspects of nuclear reactions and scattering, three body forces in nuclei, and quark physics. Comprised of four parts encompassing 145 chapters, this volume summarizes the status and results from experimental facilities such as the Bhabha Atomic Research Centre in India, TRIUMF in Canada, and the Clinton P. Anderson Meson Physics Facility in the United States. It also discusses completeness relations in scattering theory for non-Hermitian potentials, ambiguities in phase-shift analysis, and parametrization of the half-shell function when the eigenchannel has a bound state. The next chapters focus on possible phenomenological forms for the two-body local potential, nuclear three-body forces arising from triple-boson couplings, and concepts such as N-particle transit operators, three-body separable expansion amplitude, the three-body problem with energy-dependent potentials, and the four-body problem. The book also introduces the reader to triton with realistic potentials, backward proton-deuteron scattering, and deep inelastic lepton-nucleon interactions at high energy. This book will benefit physicists, students, and researchers who want to learn about the dynamics of few body systems.
