We study the tensor structure function $b_1\xq$ in deep inelastic scattering(DIS) of an electron from a polarized deuteron target. We model theelectron-nucleon cross section at the starting point for $Q^2$ evolution byvector-meson-dominance (VMD). Shadowing due to the double-scattering of vectormesons, along with the presence of a d-state admixture in ground state deuteronwave function gives rise to a non-vanishing contribution to $b_1\xq$. Althoughsignificant at large Bjorken $x$, the restoration of rotational symmetry forsmall $x$ ($\leq10^{-3}$) requires that $b_1^{(2)}\xq$ approach zero as $x\to0$ in this model. If the model is valid, it should apply within the range ofpresent fixed target experiments.Comment: 15 pages, 5 figures, BoxedEPS, REVTeX; correspondence to  jaffe@mitlns.mit.edu ; discussion of impact parameter dependence of shadowing  has been corrected, confirming a more significant enhancement of $b_1$ at  small-x, figures have been change
