Abstract

M-4,M-5 subshells average fluorescence yields ((w) over bar (M4,5)) have been determined for thorium and uranium using M-4,M-5 X-ray production cross-sections at 5.96 keV incident photon energy. The measurements have been performed using a Fe-55 annular source and an Ultra-LEGe detector. The present values are compared with calculated theoretical values and theoretical average M shell fluorescence yields ((w) over bar (M)). Fair agreement (to within 22-27%) is typically obtained between present average fluorescence yields ((w) over bar (M4,5)) and calculated theoretical values.
