Short-range correlations in (e,e${}^{\prime }$p) and (e,e${}^{\prime }$pp) reactions on complex nuclei

Abstract

The influence of short-range correlations (SRC) on the triple-coincidence (e,e${}^{\prime }$pp) 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 intermediate ${\Delta }_{33}$ currents. The (e,e${}^{\prime }$pp) cross sections are predicted to exhibit a sizeable sensitivity to the SRC. The contribution from the two-nucleon breakup channel to the semi-exclusive ${}^{12}$C(e,e${}^{\prime }$p) cross section is calculated in the kinematics of a recent NIKHEF-K experiment. In the semi-exclusive channel, a selective sensitivity in terms of the missing energy and momentum to the SRC is found.
