Summary

The successful acceleration of unpolarized Helium-3 nuclei by the AGS at
BNL heralds the possibility of achieving polarized He-3 ions at the AGS
and RHIC. Assessing the level of polarization will be a challenge at high
energy as the inelastic channels associated with He-3 scattering off a
carbon target in the electromagnetic hadronic interference region may
dilute expectations by comparison with the successful use of this method
for proton polarimetry. The large anomalous magnetic moment of He-3 is
helpful however, though the greater hadronic elastic cross section reduces
the optimal analyzing power. Encouragement may be drawn from measurements
indicating little high energy spin ...
