Sodium X-ray emission spectra of NaCl powder were measured by wavelength-dispersive X-ray fluorescence spectrometry and electron probe microanalysis. The X-ray emission spectra show an oscillating fine structure similar to that of the extended X-ray absorption fine structure (EXAFS). The Fourier transform of the X-ray fluorescence spectrum shows a similar radial distribution of atoms around the sodium. These findings demonstrate that a wavelength-dispersive X-ray emission spectrometer is a powerful tool for analyzing the local structure around a light element in condensed matter, which is still not an easy task with using a third-generation synchrotron radiation facility.
