Meson Exchange Currents in (e,e'p) recoil polarization observables

Abstract

A study of the effects of meson-exchange currents and isobar configurations in $A(\vec{e},e^{\prime }\vec{p})B$ reactions is presented. We use a distorted wave impulse approximation (DWIA) model where final-state interactions are treated through a phenomenological optical potential. The model includes relativistic corrections in the kinematics and in the electromagnetic one- and two-body currents. The full set of polarized response functions is analyzed, as well as the transferred polarization asymmetry. Results are presented for proton knock-out from closed-shell nuclei, for moderate to high momentum transfer.
