Abstract

We study the effects of nuclear shadowing and the subsequent enhancement for the spin structure function g_1A(x, Q²) in polarized DIS on ⁷Li and ³He. These effects are found to be quite significant - the magnitude of nuclear shadowing at x ≈ 10^-3 is of order 16% for g^{n.s. 3/2}_1A=7(x, Q²)/g^n.s._1N(x, Q²) and 10% for g^n.s_1A=3(x, Q²);/g^n.s._1N(x, Q²); the enhancement at x ≈ 0.125 (0.15) is of order 20 (55)% for g^{n.s. 3/2}_1A=7(x, Q²)/g^n.s._1N(x, Q²) and 14 (40)% for g^n.s._1A=3(x, Q²)/g^n.s._1N(x, Q²).
