| Abstract: | We consider the effect of the transitions n→Δ0 and p→Δ+ in deep inelastic scattering on polarized 3He on the extraction of the neutron spin structure function g1n(x,Q²). 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 g1ⁿ(x,Q²) by 15-30% in the range 0.2<~x<~0.6, where our considerations are applicable and the data for g1ⁿ(x,Q²) exist. |
