Determination of K shell X-ray intensity ratios for some heavy elements

The K shell X-ray intensity ratios Kα2/Kα1, Kβ1,3/Kα1 and Kβ2/Kα1 for 21 elements with 65⩽Z⩽92 have been measured using an incident photon energy of 123.6 keV. The X-rays have been measured with a Si(Li) semiconductor detector. Kβ and Kα X-rays have been analyzed into the components Kβ1,3 and Kβ2 and Kα1 and Kα2, respectively, using a computer program. The experimental results were compared with the theoretical values of Scofield and available experimental results. All X-ray intensity ratios values have been plotted versus atomic number.
