Abstract

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< Q2 < 70 GeV2 is covered. For values of x less than 0.002 both ratios indicate saturation of shadowing at values compatible with photoabsorption results.
