Measurement of M‐shell x‐ray production cross‐sections using 5.96‐keV photons

Abstract

Abstract M‐shell x‐ray production/fluorescence (M XRF) cross‐sections for five elements with 81 ≤ Z ≤ 92 were measured at 5.96‐keV incident photon energy using thin targets. From the measured M XRF cross‐sections the average M‐shell fluorescence yields were derived. Experimental results for XRF cross‐sections and fluorescence yields were compared with theory. The experimental results were found to be higher than the theoretical values by 10–17%. Further experimental investigations on M XRF cross‐sections for more elements at different excitation energies are required in order to check the validity of the theoretical parameters used to calculate the M XRF cross‐sections.
