Polarization degrees-of-freedom in electronuclear hadron production from finite nuclei

Abstract

The polarization degrees-of-freedom in electronuclear two-nucleon knockout reactions are discussed. Model calculations for the unpolarized ${}^{16}$O(e,e${}^{\prime }$pp) cross sections at ($\mid \vec{q}\mid$,$\omega$)=(210 MeV,300 MeV/c) are compared to recently obtained data. Predictions for the polarization observables in electronuclear two-nucleon knockout are presented. It is stressed that detailed studies of two-nucleon emission processes permit to constrain the contribution from two-nucleon mechanisms (like meson-exchange and isobar effects) to the single-nucleon knockout channel (e,e${}^{\prime }$p).
