We've made the first spin asymmetry measurement on a transversely 
polarized 3He target in semi-inclusive deep-inelastic scattering. The 
Collins and Sivers moments were extracted from the angular dependence of 
the measured target single-spin asymmetries. Beam and target double-spin 
asymmetries are also measured. The corresponding spin asymmetries of 
neutron are extracted using the nucleon effective polarization and the 
measured cross section ratio of proton to 3He. *
