Abstract
A structure analysis of the clean (001) surface of body-centred cubic iron by low-energy electron diffraction (LEED) is described. The surface was cleaned by a series of argon-ion bombardments followed by annealing treatments. The intensity analysis of 16 non-degenerate beams at three angles of incidence in the energy range from about 30 to 160 eV revealed that the structure of Fe (001) essentially corresponds to simple truncation of the bulk, with a probable contraction of 1.4% in the first interlayer spacing compared to bulk. The uncertainty in this figure, however, is +or-3% of the interlayer spacing.Keywords
