Abstract

K-shell fluorescence yields of low and medium Z elements were determined using Si-PIN diode detector employing reflection geometry set up. Target atoms were excited using 59.5 keV gamma rays emerging from Am-241 source of strength 300 mCi. Background radiation and multiple scattering effects were minimized by properly shielding the detector. The elemental foils of uniform thickness and 99.9% purity were used in the present investigation. The emitted fluorescent X-rays were detected using Si PIN diode detector. The fluorescent spectra were recorded in an 8 K multi channel analyzer. The data were carefully analyzed and total K-shell fluorescence yields were calculated. The resulting yield values are compared with the available experimental and theoretical values.
