The nuclear effects in the spin-dependent structure function g1 of the deuteron are studied in the kinematics of future experiments at CEBAF, (ν≤3GeV,Q2≤2GeV2
Nearby in the stack
). The magnitude of the nuclear effects is found to be significantly larger than the one occurring in deep inelastic scattering (
ν→∞,Q2→∞
). 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
Q2
dependence of the Gerasimov-Drell-Hearn Sum Rule for the neutron are drawn.
