Abstract
The Q(2) dependence of the structure function ratio F-2(Sn)/F-2(C) for 0.01 < x < 0.75 and 1 < Q(2) < 140 GeV2 is reported. For x < 0.1 the size of shadowing decreases linearly with In Q(2) and the maximum rate is about 0.04 at x = 0.01. The rate decreases with x and is compatibl e with zero for x greater than or equal to 0.1. The difference R(Sn) - R(C), where R is the ratio of longitudinally to transversely polarise d virtual photon absorption cross sections, is also given. No dependen ce on x is seen and the average value is 0.040 +/- 0.021 (stat.) +/- 0 .026 (syst.) at a mean Q(2) of 10 GeV2.
