Measurements of L1 and L2 Subshell Fluorescence Yields for Dy at 22.6 keV Incident Photon Energy

Abstract

The L1 and L2 subshell fluorescence yields have been deduced from the measured cross sections for production of Ll, Lα, Lβ1,4, Lβ3,6, Lβ2,15,9,10,7, Lγ1,5 and Lγ2,3,4 x-rays of Dy66 at 22.6 keV incident photon energy. These measurements were performed using a sealed point (3mm φ) radioactive source of Cd109 (20 mCi) as a photon source and Peltier cooled x-ray detector arranged in reflection geometry. The present deduced values of fluorescence yields are compared with the DHS model based theoretical values, the semi-empirical values, and those recommended by Campbell.
