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

摘要

A study of the total cross section for polarized proton knockout in$(e,e'{\vec p})$ reactions is carried out for the closed-shell nucleus$^{40}$Ca. The dependence of FSI effects on polarization observables viewed asfunctions of the nucleon polarization angles is analyzed and interpreted withinthe basis of a semi-classical model for the orbit of the struck nucleon andtrajectory of the ejected nucleon. A comparison with the case of a $^{39}$Kpolarized target and unpolarized protons is performed.
