On the extraction of the neutron spin structure functions and the Gerasimov-Drell-Hearn integral from the process

Nuclear effects in polarized inelastic electron scattering off polarized 3He are discussed; in the kinematics of future experiments at TJNAF, 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, a simple and workable equation relating the Gerasimov-Drell-Hearn Integral for the neutron to the corresponding quantity for 3He is proposed.
