“…Using the deuteron wave functions derived from the Bonn model, Arenhövel and coworkers [80] find a good agreement between theory and experiment for A(Q 2 ), B(Q 2 ), and T 20 (Q 2 ) up to Q 2 = 30 fm −2 . Very recently, the tensor polarization T 20 (Q 2 ) has been measured up to Q 2 = 45 fm −2 at the Jefferson Laboratory [81].…”

High-precision, charge-dependent Bonn nucleon-nucleon potential

We present a charge-dependent nucleon-nucleon (N N ) potential that fits the world proton-proton data below 350 MeV available in the year of 2000 with a χ 2 per datum of 1.01 for 2932 data and the corresponding neutron-proton data with χ 2 /datum = 1.02 for 3058 data. This reproduction of the N N data is more accurate than by any phase-shift analysis and any other N N potential. The charge-dependence of the present potential (that has been dubbed 'CD-Bonn') is based upon the predictions by the Bonn Full Model for charge-symmetry and charge-independence breaking in all partial waves with J ≤ 4. The potential is represented in terms of the covariant Feynman amplitudes for one-boson exchange which are nonlocal. Therefore, the off-shell behavior of the CD-Bonn potential differs in a characteristic and well-founded way from commonly used local potentials and leads to larger binding energies in nuclear few-and many-body systems, where underbinding is a persistent problem.

Electromagnetic structure of A=2 and 3 nuclei and the nuclear current operator

Different models for conserved two-and three-body electromagnetic currents are constructed from two-and three-nucleon interactions, using either meson-exchange mechanisms or minimal substitution in the momentum dependence of these interactions. The connection between these two different schemes is elucidated. A number of low-energy electronuclear observables, including (i) np radiative capture at thermal neutron energies and deuteron photodisintegration at low energies, (ii) nd and pd radiative capture reactions, and (iii) isoscalar and isovector magnetic form factors of 3 H and 3 He, are calculated in order to make a comparative study of these models for the current operator. The realistic Argonne v18 two-nucleon and Urbana IX or Tucson-Melbourne three-nucleon interactions are taken as a case study. For A=3 processes, the bound and continuum wave functions, both below and above deuteron breakup threshold, are obtained with the correlated hyperspherical-harmonics method. Three-body currents give small but significant contributions to some of the polarization observables in the 2 H(p, γ) 3 He process and the 2 H(n, γ) 3 H cross section at thermal neutron energies. It is shown that the use of a current which did not exactly satisfy current conservation with the two-and three-nucleon interactions in the Hamiltonian was responsible for some of the discrepancies reported in previous studies between the experimental and theoretical polarization observables in pd radiative capture.

The Bates Large Acceptance Spectrometer Toroid (BLAST) experiment was operated at the MIT-Bates Linear Accelerator Center from 2003 until 2005. The experiment was designed to exploit the power of a polarized electron beam incident on polarized targets of hydrogen and deuterium to measure, in a systematic manner, the neutron, proton, and deuteron form factors as well as other aspects of the electromagnetic interaction on few-nucleon systems. A brief description of the experiment is provided, together with presentation and discussion of the numerous results obtained.
