摘要：

The structure of the reconstructed Ir(110)-(1 x 2) surface has been analyzed by low-energy electron diffraction. Three models proposed for the reconstructed Ir(110)-(1 x 2) surface - the missing row model, the paired row model and the buckled surface model - were tested. Based on a comparison between experimental data consisting of intensity-voltage profiles for ten half-order beams and eight integral-order beams and the calculated curves, the missing row model with a topmost interlayer spacing of 1.22 ± 0.07 Å is the preferred structure. © 1979.
