Analysis of measured elastic low energy electron diffraction (ELEED) intensities from GaAs(110) reveals that the relaxations parallel to the surface associated with a ω1=29° bond‐length‐conserving rotated surface structure can be reduced by 75% without substantially affecting the quality of the model description of these intensities. Optimizing the surface geometry while constraining the atomic displacements parallel to the surface to be zero, however, leads to a significantly inferior description of these data. A model embodying greatly reduced but nonzero parallel displacements is compatible both with the ELEED intensities and with recent ion channeling data.
