The ratio of deep-inelastic structure functions of nuclear targets to the sum of free neutron and proton structure functions has been calculated, using a modified form of the Atwood-West technique for deuterium. Fermi-gas momentum distributions were used with modifications to include high-momentum tails resulting from nucleon-nucleon correlations. Tables of smearing ratios for W/sub 1/, W/sub 2/, and W/sub 3/ are given as a function of x and Q/sup 2/ for deuterium and several heavy nuclei. We find that for x>0.5 the scaling violations for heavy nuclei are smaller than those for free nucleons. The shapes of the antiquark distributions are also changed.
