Test of Time-Reversal Invariance in Elastic Electron Scattering from the Deuteron

A test of time-reversal invariance for an electromagnetic interaction at high momentum transfer has been performed by measuring the recoil-deuteron vector polarization for the elastic scattering of electrons from an unpolarized deuteron target for an incident electron energy of 1 GeV and a recoil-deuteron four-momentum of $q=721\mathrm{}$ MeV/c. The value obtained for the vector polarization is $\mathrm{}\left|P\right|=0.075\mathrm{}\pm 0.088$, showing no significant $T$ nonconservation.
