Abstract
Results from a low-energy electron diffraction (LEED) analysis of the A1(110) surface are presented and discussed. The results indicate that a multilayer relaxation exists in the A1(110) surface region such that the spacing between layers 1 and 2 has a relative change of -8.5% from the bulk value, while , , and . When these results are compared with those from an independent LEED analysis, excellent agreement is found between results for and . However, a disagreement is found to exist between the results of the two analyses for . When this disagreement is considered in relationship to predictions of a recent theory for the multilayer relaxation of metallic surfaces, the importance of future work to resolve this discrepancy is apparent.
