摘要：

The K-shell fluorescence yields for potassium and calcium compounds were investigated using a Si(Li) Xray detector system (FWHM = 155 eV at 5.9 keV). The target samples were excited using 59.5 keV gamma rays from an Am-241 annular source of strength 75 mCi. Chemical effects on K-shell fluorescence yield for potassium and calcium were observed. The values were compared with theoretical values of pure potassium and calcium. (C) 2004 Elsevier Ltd. All rights reserved.
