### Abstract

We consider the effect of the transitions n→Δ^{0} and p→Δ^{+} in deep inelastic scattering on polarized ^{3}He on the extraction of the neutron spin structure function g_{1}^{n}(χ,Q^{2}). Making the natural assumption that these transitions are the dominant non-nucleonic contributions to the renormalization of the axial vector coupling constant in the A = 3 system, we find that the effect of Δ increases g_{1}^{n}(χ,Q^{2}) by 15-30% in the range 0.2 ≤χ≤0.6, where our considerations are applicable and the data for g_{1}^{n}(χ,Q^{2}) exist.
