Spin-polarized low-energy electron diffraction measurements of the analyzing power of two specular beams and the (0, 1/2) beam were presented. A theoretical argument related the analyzing power S and polarizing power P of these beams for an unreconstructed Au (110) surface. This was used to deduce the symmetry of the reconstructed surface. In particular, these results were inconsistent with the missing- and pairing-row models, suggesting rotation within the reconstructed unit cell.
