Query: The Structure Function Ratios F2(Li)/F2(D) and F2(C)/F2(D) at small x   We present the structure function ratios F2(Li)/F2(D) and F2(C)/F2(D)
measured in deep inelastic muon-nucleus scattering at a nominal incident muon
energy of 200 GeV. The kinematic range 0.0001 < x < 0.7 and 0.01< Q^2 < 70
GeV^2 is covered. For values of $x$ less than $0.002$ both ratios indicate
saturation of shadowing at values compatible with photoabsorption results.
