TLDR
In this paper, the pion exchange current contribution to the thermal neutron proton radiative capture cross section is calculated on the basis of potential theory by extracting a local "absorptive exchange potential" from the corresponding fourth order Feynman diagram with the deuteron nucleon vertex on the mass shell.About:

Nucleon resonance in nuclei
TL;DR: A detailed account of the techniques used to generate these resonance configurations from the purely nucleonic configurations is given in this paper, where two-and three-nucleon systems in which the resonance configurations appear to play a role are discussed.

Mesonic processes in deep-inelastic electron scattering from nuclei
TL;DR: Inelastic electron scattering is considered in the energy and momentum transfer region associated with the quasielastic and 3-3 resonance pion electroproduction peaks in this paper, and the MEC contribution is found to be significant in this region, and helps to account for the discrepancy between theory and experiment.

Exchange currents in electron scattering from light nuclei
TL;DR: In this article, the effects of meson exchange currents on elastic and inelastic electron scattering from nuclei are considered with specific applications to 3 He, 6 Li, 7 Li, 9 Be and 10 B.

Pion exchange currents and isobar configurations in deuteron electro-disintegration below pion threshold
TL;DR: In this paper, the influence of meson exchange currents and isobar configurations on the electrodisintegration of the deuteron has been investigated for excitation energies below pion threshold and momentum transfer up to q 2 = 14 fm −2.
Journal ArticleDOI
An introduction to exchange effects in nuclei
TL;DR: The conventional picture of the atomic nucleus describes it as a collection of nucleons interacting through the strong two-body internucleon potential, and the properties of this potential have, to a large degree, been determined from data on nucleon-nucleon scattering and these properties are reasonably well understood in terms of the mesonexchange description first put forward by Yukawa as discussed by the authors.

Deuteron photodisintegration and n-p capture below pion production threshold☆☆☆
TL;DR: In this article, a nonrelativistic, phenomenological treatment of deuteron photodisintegration and radiative n-p capture is presented, where the only approximations made are the neglect of nucleon structure, pion exchange currents, and multipoles higher than the octupole.

THE INTERACTION EFFECT IN n-p CAPTURE
TL;DR: In this article, a nonrelativistic prediction of the n-p capture cross section at a neutron laboratory velocity of 2200 m/sec is evaluated as 302.5±4.0 mb assuming that r s np = 2.73±0.03 fm as predicted by charge independence.

TL;DR: In this paper, absolute differential cross-sections for elastic scattering of 27.5 MeV deuterons by Mg, V, Fe, 58 Ni, Co, 65 Cu, Ag, Au and 208 Pb were measured from 15° to 140°.

Exchange current and deuteron photodisintegration at threshold
F. Kaschluhn,K. Lewin +1 more
TL;DR: The contribution of meson exchange current to the deuteron photodisintegration amplitude at threshold is calculated by taking into account the next nearby singularities beyond the nucleon exchange poles in the crossed channels as discussed by the authors.

Application of dispersion relations to the photodisintegration of the deuteron
Bunji Sakita,Charles J. Goebel +1 more
TL;DR: In this article, the authors considered the dispersion of the matrix element of the process gamma + d − n + p by dispersion techniques and derived the Born terms of the dipole amplitudes, and solved the problem in a low energy approximation in which the n-p final state rescattering is taken into account, but no other higher order effects.
