Polarization observables in electronuclear two-nucleon knockout

Differential (e,e'pp) measurements are presently recognized as a way of stu dying short-range correlations in finite nuclei. The ((e) over right arrow, e'(p) over right arrow p) and ((e) over right arrow,e'(p) over right arrow n) differential cross section and polarization observables are studied in a microscopic model that accounts for the short-range correlations, outgoing -nucleon distortions, meson-exchange and Delta-isobar currents. It is point ed out that polarization observables represent an attractive alternative fo r absolute electronuclear two-nucleon knockout measurements. In the polariz ation transfer P-t' for ((e) over right arrow,e'(p) over right arrow p), th e effect of central short-range correlations is predicted to be large while at the same time the final-state interaction effects are small.
