We have investigated the propagation of a baryon in the exclusive process A(e,e'p)B in few-nucleon systems using realistic nuclear wave functions and Glauber multiple scattering theory both in its original form and within a generalized eikonal approximation. New results for the processes 3He(e,e'p)2H and 4He(e,e'p)3H are compared with data recently obtained at the Thomas Jefferson Laboratory (JLAB).8 pages, 9 figures, Presented at the Fifth International Conference on Perspectives in Hadronic Physics -Particle-Nucleus and Nucleus-Nucleus Scattering at Relativistic Energies-, 22 - 26 May 2006, Trieste, ItalyNuclear Theorytext
