Abstract

Changes in the measured x-ray intensities caused by the presence of nonradiative transitions are not taken into account in the correction procedures used in electron probe x-ray microanalysis (EPMA). The author reviews for L lines which physical quantities are affected by the nonradiative transitions, how conventional EPMA can be successful without incorporating these effects, when the introduction of an effective fluorescence yield is an exact solution, and in which cases the subshells are to be calculated separately and the nonradiative transitions are to be explicitly incorporated.
