On the Extraction of the Neutron Spin Structure Functions and the Gerasimov -- Drell -- Hearn Integral from ${}^3\overrightarrow{He}(\vec{e},e^{\prime })X$ data

Abstract

Nuclear effects in polarized inelastic electron scattering off polarized ${}^{3}He$ are discussed; in the kinematics of future experiments at CEBAF, 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 ${}^{3}He$ is proposed.
