Proton Propagation Through Nuclei And The Quasi-Free Reaction Mechanism Studied With (E,E ' P) Reactions.

Jefferson Lab experiment E91-013 measured the energy dependence of proton propagation in nuclei, using the quasi-free (e,e'p) reaction. The ratios of the experimental (e,e'p) cross-sections integrated over the quasi-free region to PWIA calculations are presented as a function of momentum transfer, (0.6 < Q(2) < 3.3 GeV2) and target nucleus (C, Fe and Au). As a first step towards a longitudinal and transverse separation of the quasi-free cross-section, a super ratio of the measured to the calculated cross-sections at forward and backward angles is presented.
