Final-state interaction and recoil polarization in (e,e′p) reactions: comparison with the polarized target case

A study of the total cross section for polarized proton knockout in (e,e′p→) reactions is carried out for the closed-shell nucleus 40Ca. The dependence of FSI effects on polarization observables viewed as functions of the nucleon polarization angles is analyzed and interpreted within the basis of a semi-classical model for the orbit of the struck nucleon and trajectory of the ejected nucleon. A comparison with the case of a 39K polarized target and unpolarized protons is performed.
