Abstract

We analyse the proton and deutron data on spin dependent asymmetry A₁(x,Q²) supposing the DIS structure functions g₁(x,Q²) and F₃(x,Q²) have the similar Q²-dependence. As a result, we have obtained Γ₁^p - Γ₁ⁿ = 0.192 at Q²= 10~\rm GeV² and Γ₁^p - Γ₁ⁿ = 0.165 at Q²= 3~\rm GeV², in the best agreement with the Bjorken sum rule predictions.
