  The semi-inclusive deep inelastic scattering of electrons off a nucleus A
with detection of a slow nucleus (A-1) in the ground or low excitation states,
i.e. the process A(e,e'(A-1))X, can provide useful information on the origin of
the EMC effect and the mechanisms of hadronization. The theoretical description
of the process is reviewed and the results of several calculations on few-body
systems and complex nuclei are presented.
