Abstract

The contributions from 12C(e,e'pn) and 12C(e,e'pp) to the semi-exclusive 12C(e,e'p) cross section have been calculated in an unfactorized model for two-nucleon emission. We assume direct two-nucleon knockout after virtual photon coupling with the two-body pion-exchange currents in the target nucleus. Results are presented at several kinematical conditions in the dip and Δ(1232) regions. The calculated two-nucleon knockout strength is observed to account for a large fraction of the measured (e,e'p) strength above the two-nucleon emission threshold.
