Spin-dependent correlations and the semi-exclusive 16O(e,e′p) reaction Original Research Article

The effect of central, tensor and spin–isospin nucleon–nucleon correlations upon semi-exclusive View the MathML source reactions is studied for Q2 and Bjorken x values in the range View the MathML source and 0.15≲x≲2. The fully unfactorized calculations are performed in a framework that accounts not only for the dynamical coupling of virtual photons to correlated nucleon pairs but also for meson-exchange and View the MathML source-isobar currents. Tensor correlations are observed to produce substantially larger amounts of semi-exclusive View the MathML source strength than central correlations do and are predominantly manifest in the proton–neutron knockout channel. With the exception of the x≈2 case, in all kinematical situations studied the meson-exchange and isobar currents are a strong source of A(e,e′p) strength at deep missing energies. This feature gives the A(e,e′p) strength at deep missing energies a pronounced transverse character.
