Relative Intensities of Ka Satellites in X-Ray Fluorescence Spectra of Na, Mg, Al and Si

Abstract

A plane crystal spectrometer was used to measure relative integrated intensities of K_α X-ray satellites in fluorescence spectra of Na in NaF, and of Mg, Al, Si in metals and oxides. A comparison between the measured intensity of the Κ_α'α3α4 satellite group and the intensity obtained from electron excitation measurements indicates that the production probability of KL double-hole states is independent of the excitation mode. The measured intensities in metals are in agreement with calculated intensities based on the sudden approximation theory of x-ray satellites of free neon-like ions. The bond in fluoride and oxides was shown to increase the relative intensity by about 13%. From intensity considerations, the Κ_α5α6 satellite group was attributed to KL² triplehole states.
