Quark-Hadron Duality in Neutron Spin-Structure and g_2 moments at intermediate Q**2
Jefferson Lab experiment E01-012 measured the He-3 spin-structure functions and virtual photon asymmetries in the resonance region in the momentum transfer range 1.0<4.0(GeV/c)**2. Our data, when compared with existing deep inelastic scattering data, were used to test quark-hadron duality in g_1 and A_1 for He-3 and the neutron. In addition, preliminary results on the He-3 spin-structure function g_2, on the Burkhardt-Cottingham sum rule and on higher twist effects through the x**2-weighted moment d_2 of the neutron were presented.
