Measurement of L subshell X-ray fluorescence cross sections and L subshell fluorescence yields for elements in the atomic range 73 ≤ Z ≤ 92 at 60 keV

Li (i = 1, 2 and 3) X-ray fluorescence cross sections have been measured for ten elements in the atomic range 73 ≤ Z ≤ 92 at 60 keV. The values of Li subshell fluorescence yields (ω1, ω2 and ω3) have been measured for the same elements using the presently measured cross section values and the theoretical Li subshell photoionisation cross sections, Coster-Kronig transition probabilities and emission rates. The measured X-ray fluorescence (XRF) cross section values are in general agreement with the theoretical values evaluated using L subshell fluorescence yields, Coster-Kronig transition probabilities, emission rates and subshell photoionisation cross sections. Furthermore, the values of L subshell fluorescence yields are in good agreement with the theoretical values. (author)
