We present experimental results of the first high-precision test of quark-hadron duality in the spin-structure function g1 of the neutron and He3 using a polarized He3 target in the four-momentum-transfer-squared range from 0.7 to 4.0(GeV/c)2. Global duality is observed for the spin-structure function g1 down to at least Q2=1.8(GeV/c)2 in both targets. We have also formed the photon-nucleon asymmetry A1 in the resonance region for He3 and found no strong Q2 dependence above 2.2(GeV/c)2.
