Abstract

The study aimed to determine the chemical effects on the K and L X-ray intensity ratios and the K and L X-ray production cross sections for gold compounds. The K shell fluorescence yields and L shell average yields were also investigated. The samples were excited by 59.5 keV gamma-rays from an (241)Am annular radioactive source and 123.6 keV gamma-rays from a (57)Co annular radioactive source. K and L X-rays emitted from samples were counted by an Ultra-LEGe detector with a resolution of 0.150 keV at 5.9 key. The experimental values were compared with theoretical, the semi-empirical and other experimental values. (C) 2010 Elsevier Ltd. All rights reserved.
