Quasifree(e,e′p)Reactions and Proton Propagation in Nuclei

The ( ${e,e}^{\prime }p$) reaction was studied on targets of C, Fe, and Au at momentum transfers squared $Q^2$ of 0.6, 1.3, 1.8, and $3.3{\mathrm{GeV}}^2$ in a region of kinematics dominated by quasifree electron-proton scattering. Missing energy and missing momentum distributions are reasonably well described by plane wave impulse approximation calculations with $Q^2$ and $A$ dependent corrections that measure the attenuation of the final state protons.
