According to perturbative QCD, nuclear quasiexclusive reactions should be A1 at asymptotically large momentum transfer. Here we analyze how the asymptotic prediction is modified at finite energies by the expansion of the quark systems as they become hadrons and exit from the nucleus. We find that the phenomenon of nuclear transparency should be apparent in presently fesible experiments, but the degree of transparency is sensitive to the expansion model.
