Body text

X-ray fluorescence (XRF) analyses with 116 keV X-rays as an excitation source is suitable for nondestructive multielemental analyses of heavy elements such as rare-earth elements. It also should be useful for nondestructive analyses of rare-earth and heavy elements in geological, geochemical and archaeological samples as well as industrial materials. This shows a plot of intensities of Ba, Nd and Ce Ka lines. There is significant difference between three kinds of antique ceramics, made in Arita, Himetani, and Kutani. The intensities of Ba, Nd and Ce Ka lines showed significant dependence on the place of potteries.

Technique

The high-energy X-rays emitted from the wiggler and monochromatized by Si400 bent monochromator is injected to the sample. The fluorescence X-rays are detected by a Ge solid state detector.
