摘要：

L-shell X-ray production cross-sections have been measured for selected heavy elements with 70 less than or equal to Z less than or equal to 92 at 59.54 keV using a Si( Li) detector. The L-subshell X-ray fluorescence yields omega (1), omega (2) and omega (3) have been derived using the experimental L X-ray production cross-sections, theoretical L-subshell photoionization cross-sections, Coster-Kronig transition probabilities and fractional X-ray emission rates. The data obtained are compared with the literature experimental data, theoretical predictions based on Dirac-Hartree-Slater wave functions and semi-empirical compilations.
