The structure and hyperfine magnetic properties of epitaxial Fe ultrathin films on a vicinal Pds110d surface have been investigated by means of low-energy electron diffraction sLEEDd, reflection high-energy electron diffraction sRHEEDd and Fe conversion electron Mössbauer spectroscopy sCEMSd. LEED and RHEED provide evidence for initial pseudomorphic film growth. The RHEED determination of the i...

We studied the early stages of Gd2O3 epitaxy on Si(111) in real time by synchrotron-based, high-resolution X-ray diffraction and by reflection high-energy electron diffraction. A comparison between model calculations and the measured X-ray scattering, and the change of reflection high-energy electron diffraction patterns both indicate that the growth begins without forming a three-dimensional c...

The structures of cyanogen and diacetylene have been previously investigated by the electron-diffraction method by Wierl,I who reported nonlinear models with 1500 bond angles for both molecules. The improbability of this conclusion, which is incompatible with all other evidence for the angle between a triple and a single bond on the same carbon atom, led to a reinvestigation of these compounds ...

Antimony cluster thin films have been synthesized by the newly-developed low energy cluster beam deposition technique. Proton-induced X-ray emission analysis shows absence of any foreign impurity even at ppm level. Structural analysis by glancing angle X-ray diffraction indicates presence of rhombohedral Sb along with Sb-oxides. Transmission electron microscopy micrographs for 20 Å and 100 Å fi...
