We have measured the neutron virtual photon asymmetry A_1~n over the kinematic range 0.33 ≤ x ≤ 0.61 and 2.8 ≤ Q~2 ≤ 4.9 (GeV/c)~2. To extract A_1~n, longitudinal and transverse spin asymmetries have been measured for inclusive ~3He(e,e') scattering, using a 5.7 GeV longitudinally polarized electron beam at Jefferson Lab and a high-density polarized ~3He target in Hall A. Preliminary results of A_1~n are presented and compared to existing data and various models, including the predictions of SU(6), broken SU(6) constituent quark models and perturbative QCD based models.
