Nucleon-Nucleon Correlations and Two-Nucleon Currents in Exclusive (e, e′NN) Reactions
It is well known that nuclei form a many-body system of interacting nucleons which exhibit strong correlations beyond the mean field or Hartree-Fock approximation. The strong short-range and tensor components of a realistic model for the nucleon-nucleon (NN) interaction induce corresponding two-body correlations. Many attempts have been made to explore the details of these correlations. Photoin...
متن کاملElectroinduced two-nucleon knockout and correlations in nuclei
We present a model to calculate cross sections for electroinduced two-nucleon emission from finite nuclei. Short-range correlations in the wave functions and mesonexchange contributions to the photoabsorption process are implemented. Effects of the short-range correlations are studied with the aid of a perturbation expansion method with various choices of the Jastrow correlation function. The m...
متن کاملElectron-nucleon cross section in (e,e'p) reactions.
We examine commonly used approaches to deal with the scattering of electrons from a bound nucleon. Several prescriptions are shown to be related by gauge transformations. Nevertheless, due to current non-conservation, they yield different results. These differences reflect the size of the uncertainty that persists in the interpretation of (e, e ′ p) experiments.
متن کاملShort-range correlations in (e,ep) and (e,epp) reactions on complex nuclei
The influence of short-range correlations (SRC) on the triple-coincidence (e,epp) reactions is studied. The non-relativistic model uses a mean-field potential to account for the distortions that the escaping particles undergo. Apart from the SRC, that are implemented through a Jastrow ansatz with a realistic correlation function, we incorporate the contribution from pion exchange and intermedia...
متن کامل0 Single particle strength restoration and nuclear transparency in high Q 2 exclusive ( e , ep ) reactions
Quenching of the single particle strength which previously precluded unambiguous measurement of nuclear transparency in quasifree (e,e'p) reactions at Q 2 ≥ 1 GeV 2 is evaluated from the cross sections of measured processes. We have demonstrated evidence of the single particle strength restoration with increase of Q 2 in the exclusive (e,e'p) reactions and argue that in practically interesting ...
