Spin Structure Function of the Deuteron in the Resonance Region and the GDH Sum Rule for the Neutron 1
The nuclear effects in the spin-dependent structure function g1 of the deuteron are studied in the kinematics of future experiments at CEBAF, (� ≤ 3 GeV, Q 2 ≤ 2 GeV 2 ). The magnitude of the nuclear effects is found to be significantly larger than the one occurring in deep inelastic scattering (� → ∞, Q 2 → ∞). We discuss the mechanism leading to large effects in the region of the nucleon resonances. A possibility to measure the neutron structure functions in the CEBAF experiments with deuterium is analysed, and conclusions about the experimental study of the Q 2 dependence of the Gerasimov-Drell-Hearn Sum Rule for the neutron are drawn.
