چکیده انگلیسی
L X-ray fluorescence cross sections of the elements with Z = 62, 64, 66, 68 and 70 have been measured at 17.8, 22.6 and 25.8 keV using an X-ray tube and secondary exciters of Mo, Ag and Sn. The measured cross sections have been compared with the theoretical predictions and with the data of others. Theoretical values calculated using photoionisation cross sections from Scofield [Lawrence Livermore Laboratory, UCRL-51326, 1973], fluorescence yields and Coster-Kronig transition probabilities from Puri et al. [X-ray Spectrom. 22 (1993) 358] and radiative widths from Campbell and Wang [At. Data Nucl. Data Tables 43 (1989) 281] show good agreement with our data. Except two sets of data on Lγ cross sections, all the data of other groups agree well with those of ours.
