Abstract: | We analyze the proton and deutron data on the spin-dependent asymmetry A 1(x, Q 2), supposing that the DIS structure functions g 1(x, Q 2) and F 3(x, Q 2) have a similar Q 2 dependence. As a result, we have found that Λ 1 p −Λ 1 n =0.190±0.038 at Q 2=10 GeV2 and Λ 1 p −Λ 1 n =0.165±0.026 at Q 2=3 GeV2; these values are in the best agreement with the Bjorken sum rule predictions.
