Abstract
The contributions from C-12(e, e'pn) and C-12(e, e'pp) to the semi-exc lusive C-12(e, e'p) cross section have been calculated in an unfactori zed model for two-nucleon emission. We assume direct two-nucleon knock out after virtual photon coupling with the two-body pion-exchange curr ents in the target nucleus. Results are presented at several kinematic al conditions in the dip and DELTA (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 thres hold.
