Abstract

K -Shell Fluorescence Yields of elements with atomic number z ranging from 26 to 50 ( 26 ≤ z ≤ 50 ) were determined using Si(PIN) and HPGe detector employing reflection geometry set up. Target atoms were excited using 59.54keV gamma rays emerging from Am-241 source of strength 300mCi. 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 fluorescent spectra were recorded in 8K and 16K multi channel - analyzers. The data were carefully analyzed and K-shell fluorescence yields were calculated. The resulting yield values are compared with the available experimental and theoretical values
