  Since a long time electron scattering has been envisaged as a powerful and
preferential tool to investigate nuclear properties. In particular, the (e,e'p)
knockout reaction has provided a wealth of information on the single particle
(s.p.) aspects of nuclear structure, on the validity and the limit of the
independent particle shell model. The work done for electron scattering is
extremely useful also for the analysis and the interpretation of neutrino
oscillation experiments, where nuclei are used as neutrino detectors and it is
crucial that nuclear effects in neutrino-nucleus interactions are well under
control. In this contribution it is discussed if and how the work done for
(e,e'p) can be exploited for the analysis of neutrino-nucleus scattering data.
