Abstract
We investigate the non-perturbative effects on the ratio R = sigma(L)/ sigma(T) in lepton-nucleon deep inelastic scattering by taking into ac count the lowest dimensional condensate contributions som the QCD vacu um. By combining conventional perturbative QCD corrections and the Geo rgi-Politzer target-mass effects with the non-perturbative effects fro m the QCD vacuum, we give a good description of the Q(2) and x depende nces of R in comparison with the recent experimental data.
