X-Ray Spectroanalysis of Light Elements Using H^3/Zr as Exciting Source

概要

論文の詳細を見る
The capability of a device for the X-ray spectroanalysis is studied which essentially consists of a H^3/Zr source, a helium-filled specimen chamber and a proportional counter equipped with a thin plastic window. The best results can be obtained with a 0.46mg/cm^2 polycarbonate window which allows the transmission of soft X-ray below 1 keV but stops the β-rays emitted from the source and scattered towards the window. It is shown that both the X- and β-rays from the H^3/Zr source are effective in exciting the characteristic X-rays of light elements (Na, Mg, Al and Si) and the X-rays from the source are effective in exciting those of elements of intermediate atomic numbers (Ti, V, Cr, Mn, Fe Co and Ni). The K X-ray intensities for light elements are comparable to or higher than those for elements of intermediate atomic numbers. Two examples are given which illustrate the usefulness of this device in the X-ray spectroanalysis of light elements.
