DEUTERON SPIN STRUCTURE FUNCTIONS AT SMALL BJORKEN-X

We investigate polarized deuteron structure functions at small values of the Bjorken variable, x<0.1. In this region contributions from the coherent interaction of diffractively excited hadronic states with bot h nucleons become important. A proper treatment of this process requir es an extension of the Glauber-Gribov multiple-scattering theory to in clude spin degrees of freedom. In the kinematic domain of current fixe d target experiments we observe that shadowing effects in g(1)(d) are approximately twice as large as for the unpolarized structure function F-2(d). Furthermore at x<0.1 the tensor structure function b(1) is fo und to receive significant contributions from coherent double scatteri ng.
