High-Energy Electron-Diffraction and X-Ray Emission Analysis of Surfaces and Their Reaction Products x-ray information may be obtained from such structures simultaneously. Attempts to calibrate the apparatus for carbon and oxygen layers on iron are discussed in some detail. The method appears well suited to the study of kinetic phenomena in surface films of mean thickness less than 100 Å.

Natalia A. Baires,Mitch Frylingd earlier has been modified to improve the intensity of the secondary x-ray. The modified setup with low-Z kit has been changed to accommodate four analyzing crystals in the vacuum chamber. The radioisotopes dysprosium-159, iodine-125, and others were used with the nondispersive x-ray fluorescence m

Luc Anselin,Ibnu Syabri,Youngihn Kho to Al(NO.). was not. Therefore in the nitrous oxide flame it was possible to determine effects of Ca and Al excitation as well as the effects of Al on Ca excitation. The association of Ca ions with PO.. and SO.. in solutions to form probably CaSO. and Ca.(PO.). would be consistent with our results.
