Rescattering Contributions to Final State Interactions in (e,e'p) Reactions at High (p_m,E_m)

Abstract

The contribution of rescattering to final state interactions in the (e,e'p) cross section is studied using a semiclassical model. This approach considers a two-step process with the propagation of an intermediate nucleon and uses Glauber theory to account for the reduction of the experimental yield due to N--N scattering. This calculation has relevance for the analysis of data at high missing energies and in particular at the kinematics of the E97-006 experiment done at JLab. It is found that rescattering is strongly reduced in parallel kinematics and that the excitation of nucleon resonances is likely to give important contributions to the final state interactions in the correlated region. For heavy nuclei, further enhancement to the rescattering is expected to be generated from the strength in the mean field region.
