Si. Duimakaev et al., CALCULATION OF THE X-RAY-FLUORESCENCE INTENSITY FOR A HETEROGENEOUS POWDER SAMPLE, Industrial laboratory, 60(6), 1994, pp. 341-343
In developing the Losev - Smagunova theory, an equation for calculatin
g the intensity of x-ray fluorescence of an element of a heterogeneous
powder sample is suggested. The equation gives information both on th
e elemental content and density of a real (i.e., with porosity) sample
. An experimental verification of a semiempirical variant of the equat
ion shows the efficiency of the approach suggested.
