Separation of Electromagnetic Response Functions of Few-Body Nuclei in (e,e’p) Reactions
We report on latest results in electro-induced reactions on few-body nuclei, especially recent experimental determinations of the cross sections for the reactions 2H(e,e’p)n and 3He(e,e’p)2H for which three out of four electromagnetic structure functions have been separated. These new precise data allow a thorough study of the reaction mechanism of the (e,e’p) reaction at momentum transfers up to one GeV. The data are compared to theoretical descriptions of the (e,e’p) cross sections which include final state interactions, meson exchange currents and relativistic effects by consistently solving the scattering problem. We will discuss the relevance of FSI at low q and the importance of a relativistic treatment of the current operator at high q and the longitudinal-transverse interference structure function.
