Time-of-flight scattering and recoiling spectrometry was used to show that the reconstructed Ir(110) surface, following annealing to 1400C, consisted primarily of domains of faceted (1 x 3) structures (with two missing first-layer rows and one missing second-layer row); the data were consistent with secondary domains of (1 x 1) structures (with no missing rows). This structure was determined from scans of (i) back-scattering versus incidence angle α, (ii) forward-scattering versus α, and (iii) forward-scattering versus scattering angle.
