We have measured the beam-normal single-spin asymmetries in elasticscattering of transversely polarized electrons from the proton, and performedthe first measurement in quasi-elastic scattering on the deuteron, at backwardangles (lab scattering angle of 108 degrees) for Q2 = 0.22 GeV^2/c^2 and 0.63GeV^2/c^2 at beam energies of 362 MeV and 687 MeV, respectively. The asymmetryarises due to the imaginary part of the interference of the two-photon exchangeamplitude with that of single photon exchange. Results for the proton areconsistent with a model calculation which includes inelastic intermediatehadronic (piN) states. An estimate of the beam-normal single-spin asymmetry forthe scattering from the neutron is made using a quasi-static deuteriumapproximation, and is also in agreement with theory.
