High-resolution experimental data for the low-energy electron diffraction fine structure in W(110) are analyzed using a one-dimensional model potential barrier used previously for W(001). The measured fine structure is reproduced very well for both surfaces, and the optimum barriers are similar. The position of the image plane in W(110), however, is approximately 0.2–0.3 a.u. farther from the outermost layer of atoms than in W(001). This is in good agreement with the results of self-consistent electronic-structure calculations reported by Jepsen and Jones in the preceding paper.
