How is the deuterium target vector false asymmetry determined? One
might want to think about this since the target ONLY vector
asymmetry vanishes due to time reversal invariance under the
assumption of the 1-photon exchange approximation. It may not if
2-photon exchange effects are important. There is reason to believe
that if 2-photon exchange effects are important in ep scattering,
they may be even stronger in ed scattering due to the fact that
the deuterium continuum is only 2.2 MeV away as opposed to 140 MeV
in ep scattering.
