Low Energy Electron Diffraction (LEED) Spectra: Aluminum

The intensities of low energy electron beams specularly and nonspecularly diffracted from {100}, {110} and {111} surfaces of aluminum have been measured in a display-type LEED system as functions of electron energy, angle of incidence and azimuthal angle. Several of the measured and normalized spectra are presented, and the procedures followed in aligning the sample, reducing stray magnetic fields, and collecting and normalizing the data are described.
