[en] A first measurement of the inclusive target single-spin asymmetry, Aⁿ_y, has been performed in deep-inelastic scattering of electrons from a ³He target polarized normal to the electron scattering plane. This asymmetry is void of contributions at the Born level, and thus is a direct observable for two-photon physics. The experiment was performed in Hall A at Thomas Jefferson National Accelerator Facility from October 2008 through early February 2009. The measurement is the first from a polarized neutron target. The final overall precision is several times better than previously existing SLAC proton data, and significantly extends the kinematic range over which the asymmetry has been measured. The asymmetry was measured at five kinematic points in the deep inelastic scattering region covering Q² = 1 - 3 GeV² and x_B = 0.16 to 0.41. The asymmetry varied from 0.006 to 0.071 with astatistical precision at the 10^-2 level

[en] In this paper, I present an overview and preliminary results from three experiments at Jefferson Lab that were recently completed using a ³He gas target with polarization oriented normal to the scattering plane of unpolarized incident electrons. A target single spin asymmetry was formed by periodically flipping the direction of the target spin. In the reaction ↑³He(e,e'), the Born contribution is expected to be zero, giving direct sensitivity to two photon exchange. This asymmetry was measured in the quasi-elastic and deep-inelastic regimes with 0.1 < Q² < 1.0 GeV². The asymmetry is predicted to decrease by two-orders of magnitude for deep-inelastic versus quasi-elastic scattering. Preliminary results from these experiments will be presented.
