Abstract The isoscalar nucleon structure functionsF 2(x, Q 2) andxF 3(x, Q 2) are measured in the range 0〈Q 2〈64 GeV2, 1.7〈W 2〈250 GeV2,x〈0.7 using ν and $$\bar v$$ interactions on neon in BEBC. The data are used to evaluate possible higher twist contributions and to determine their impact on the evaluation of the QCD parameter Λ. In contrast to previous analyses reaching to such lowW 2 values, it is found that a low $$\Lambda _{\overline {MS} } $$ value in the neighbourhood of 100 MeV describes the data adequately and that the contribution of dynamical higher twist effects is small and negative.
