Abstract

Average L-shell fluorescence yields of some rare earth elements were determined using HPGe 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 fluorescent spectra were recorded in a 16 K multichannel -analyzer. The data were carefully analyzed and average L-shell fluorescence yields were calculated. The resulting yield values are compared with the available experimental and theoretical values.
