A model for calculating surface roughness effect on the intensity of emitted X-rays in the soft and ultrasoft X-ray region is presented and discussed. The results of calculations based on this model are compared to the results obtained experimentally

The Cu-Lβ/Cu-Lα x-ray emission intensity ratio of the following compounds have been found to show an interesting consistency: Cu, Cu2O, CuO, La1.85Ba.15CuO4 (vacuum annealed), La1.85Ba.15CuO4 (air annealed, TC = 26K), La1.85Sr.15CuO4 (TC = 35K), YB

Variable sample exit angle x-ray fluorescence spectroscopy (VEA-XRF) employing the Lβ/Lα intensity ratio for transition metals and their oxides has been shown to be useful for non-destructively studying transition metal surfaces and oxidation, as w

Marine ferromanganese oxide crust fragments sampled from a massive equatorial Pacific Ocean crust deposit exhibit distinct micromorphological features and a microchemical distribution which have not been previous reported. Black, shiny upper layers o

X-ray emission spectroscopy has become an increasingly more useful tool to probe the nature of the electronic structure of ionic substances. Recently, Mazalov et al.(1) have reported on the effect of cations on the X-ray emission spectra of complex a

Molecular x-ray emission spectroscopy (XES), as other valence electron spectroscopic techniques, often yields spectra which may consist of no more than a few close lying or overlapping broad bands representing a relatively large number of active tran

X-ray emission spectroscopy (XES) represents one of the many ways of obtaining useful information about the valence electron structures of molecules.(1) XES has had increasing attention as a molecular tool since the late 1960's.(2) Most of the earlie

A brief review of the general requirements for handling “real world” thin film and interfacial analysis in the thickness region of 50 to 5000 A is offered. An attempt has been made to demonstrate that variable exit angle X-ray fluorescence spectr
