A$_y$ Measurement from $^3\mbox{He}^\uparrow(e,e'n)$ Scattering at Jefferson Lab

Recently A$_y$ asymmetry measurements have been conducted in Jefferson Lab's Hall A through electron scattering from a vertically polarized $^3$He target. Experiment E08-005 measured the target single-spin asymmetry A$_y$ in the quasi-elastic $^3\mbox{He}^\uparrow(e,e'n)$ reaction. Plane wave impulse approximation (PWIA) predicts that A$_y$ should be exactly zero. A previous experiment at Q$^2$ of 0.2 (GeV/c)$^2$, where full calculations of Laget and Nagorny indicated A$_y$ to be small, showed a large asymmetry as calculated by the Bochum group using Faddeev calculations to solve the three-body problem exactly. The recent experiment measured this asymmetry at Q$^2$ of 0.1 (GeV/c)$^2$, 0.5 (GeV/c)$^2$ and 1.0 (GeV/c)$^2$. This is the first measurement of A$_y$ at large Q$^2$, which is another region where A$_y$ is expected to be small. Any non-zero result is an indication of effects beyond simple impulse approximation. This measurement will test the models used to extract neutron form factor from polarized $^3$He. Details of the measurement will be presented.
