Abstract

We have measured the beam-normal single-spin asymmetry A _n in the elastic scattering of 1-3 GeV transversely polarized electrons from H1 and for the first time from He4, C12, and Pb208. For H1, He4, and C12, the measurements are in agreement with calculations that relate A _n to the imaginary part of the two-photon exchange amplitude including inelastic intermediate states. Surprisingly, the Pb208 result is significantly smaller than the corresponding prediction using the same formalism. These results suggest that a systematic set of new A _n measurements might emerge as a new and sensitive probe of the structure of heavy nuclei.

N2 - We have measured the beam-normal single-spin asymmetry A n in the elastic scattering of 1-3 GeV transversely polarized electrons from H1 and for the first time from He4, C12, and Pb208. For H1, He4, and C12, the measurements are in agreement with calculations that relate A n to the imaginary part of the two-photon exchange amplitude including inelastic intermediate states. Surprisingly, the Pb208 result is significantly smaller than the corresponding prediction using the same formalism. These results suggest that a systematic set of new A n measurements might emerge as a new and sensitive probe of the structure of heavy nuclei.
