Recent JLab experimental data on quasi elastic 3He(e,ep)2H(pn) and 4He(e,ep)3H processes are interpreted using an approach based upon realistic wave functions and Glauber multiple scattering theory within a generalized eikonal approximation (GEA). The results of a non factorized calculation of the left-right asymmetry A_{TL} of the process 3He(e,ep)2H, obtained using the full covariant form of the electromagnetic operator, are also presented.
