Abstract

We compare the recent results on the higher twist (HT) contribution to the nonsinglet combination g₁^p - g₁ⁿ of the polarized proton and neutron structure functions with that one to the unpolarized structure function F₃ using the assumption that the HT contributions to the Gross-Llewellyn Smith and the Bjorken sum rules are similar. We have found, that the relation 1/3h^F₃(x) ≈ (6)/(g_A)h^{g₁p - g₁n}(x) is valid for x ≥ 0.2 in the case of NLO QCD approximation for the leading term parts of the structure functions.
