Role of the Delta (1232) in deep inelastic scattering on polarized He-3 and extraction of the neutron spin structure function g(1)(n)(x,Q(2)) - art. no. 014025

We consider the effect of the transitions n-->Delta (o) and p-->Delta (+) i n deep inelastic scattering on polarized He-3 on the extraction of the neut ron spin structure function g(1)(n)(x,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 Delta increases g(1)(n)(x,Q(2)) by 15-30% in the range 0.2 less than or equal to x less than or equal to 0.6, where our con siderations are applicable and the data for g(1)(n)(x,Q(2)) exist.
