Abstract
Nuclear effects in polarized inelastic electron scattering off polarized 3He and polarized 2H are discussed; in the resonance region, Fermi motion effects are found to be much larger than in deep inelastic scattering. It is shown that improperly describing nuclear dynamics would lead to the extraction of unreliable neutron spin structure functions; on the other hand side, simple and workable equations, relating the Gerasimov -- Drell -- Hearn Integral for the neutron to the corresponding quantity for 3He and 2H, are proposed. Nuclear effects in the recent E143 data are estimated by a proper procedure.File in questo prodotto:
