The atomic structure of sub-monolayer amounts of Ti deposited on the Al(100) surface at room temperature has been studied using low-energy electron diffraction (LEED) and low-energy ion-scattering spectroscopy (LEIS/ ISS). The Ti coverage was determined using Rutherford backscattering spectroscopy. From the symmetry of the observed c(2x2) LEED images we infer a structure which places the Ti atoms in every other Al unit cell. Analysis of the LEIS spectra, including both azimuth- and polar-angle scans, corroborates this hypothesis. This conclusion is relevant to recent studies of Ti as a catalyst in Na alinates presently being studied for their use in hydrogen storage applications important in fuel cell research.
