Abstract

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