摘要：

An analysis of the effects of meson exchange and isobar currents in exclusive (e,e'p) processes from O-16 under quasifree kinematics is presented. A model that has probed its feasibility for inclusive quasielastic (e,e') processes is considered. Sensitivity to final state interactions between the outgoing proton and the residual nucleus is discussed by comparing the results obtained with phenomenological optical potentials and a continuum nuclear shell-model calculation. The contribution of the meson exchange and isobar currents to the response functions is evaluated and compared to previous calculations, which differ notably from our results. These two-body contributions cannot solve the puzzle of the simultaneous description of the different responses experimentally separated. [S0556-2813(99)01207-8].
