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' (p) over right arrow) reactions is carried out for the closed-shell nucleus Ca-40. 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 K-39 polarized target and unpolarized protons is performed. (c) 2005 Elsevier B.V. All rights reserved.
