The simultaneous hydrogen and silicon atom densities in amorphous silicon, a-Si, films prepared by the glow discharge technique have been measured by 25 MeV alpha -particle elastic scattering. Integrated band intensities for the silicon-hydrogen stre

The hydrogen and oxygen content of self-supporting carbon films produced bydc glow discharge have been determined using a precise method involving the elastic scattering of 25 MeV α-particles. The number of carbon-hydrogen bonds has been determined

Unlike transmission Mossbauer spectroscopy which, in order to be of widespread utility in surface science, requires high-area solids, conversion electron Mossbauer spectroscopy (CEMS) is applicable to a wide range of low-area materials containing iro

Carbon deposits were formed on iron foils by the catalytic decomposition of an acetone-carbon dioxide mixture. These deposits were studied by Conversion Electron Mossbauer Spectroscopy and weight change measurements. The results indicate that wustite

The early stages of the oxidation of plain carbon steels has been studied by 57Fe Conversion Electron Mossbauer Spectroscopy (CEMS). The potential of the technique in elucidating the nature of new surface—and sub-surface—phases formed on massive

Phases in the spinel series Zn2+[Zn (1−x) 2 2+Sn 1+x 2 Fe1−x3+Fex2+]O4 have been prepared and studied by 57Fe and 119Sn Mossbauer spectroscopy. For 0 ⩽ x ⩽ 0.75 the spinels remain paramagnetic down to 80 K. Evidence is found for fast localize

XPS studies of the bulk oxides of lead reveal no clear evidence for the presence of the expected two oxidation states of lead in Pb3O4. They also show that the Pb 4ƒ binding energies of the two crystallographic modifications of lead monoxides are th
