L-i(i=1, 2 and 3) X-ray fluorescence cross sections have been measured for ten elements in the atomic range 73 less than or equal to 2 less than or equal to 92 at 60 keV. The values of L-i subshell fluorescence yields (omega(1), omega(2) and omega(3)) have been measured for the same elements using the presently measured cross section values and the theoretical L-i subhell 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.
