“…(4) The change of co& with increasing atomic number in this region of the periodic table is much less than that predicted by the theory and by the compilation. (5) The new experimental values of co& are approximately 20% larger than the com-piled data and 55% larger than the latest theoretical predictions for the elements with Z =80. (6) The onsets of L)-L3M5 and L, -L3M4 CK transitions are probably located at Z =75 and 78, respectively.…”

An analysis of the I x-ray spectra, induced by -50 keV electron impact and recorded with a curved crystal spectrometer, has been performed based on a calculation model that takes into account all physical events taking place during the initial ionization and inner-vacancy processes. The L-subshell fluorescence yields co&, co&, and co3 for ten elements with atomic number Z =73-83 were obtained. They are all in good agreement with recent measurements but display an appreciable disagreement with the semiempirically compiled data for the elements around Z=80. These experimental values of co& are approximately 20% larger than the compiled data and 55% larger than the latest theoretical calculation for the elements with Z =80.

“…Much experimental effort has been expended in attempts to improve our knowledge of Coster-Kronig transition probabilities for the L subshells [1]. The two main streams of experimental information were obtained by the K-L x-ray coincidence method [2][3][4][5][6][7][8][9] and the synchrotron ionization method [10][11][12][13][14][15].…”

Non-radiative transitions cause changes in the generation of the intensity of the L lines. In order to investigate the physical quantities relevant to the L lines affected by the non-radiative transitions, experimental measurements were carried out using a Si(Li) x-ray spectrometer. Atomic L shell Coster-Kronig yields (f 12 , f 13 and f 23 ) for some elements in the atomic number range 59 Z 90 were determined. These selected measured semi-empirical values were also fitted by least squares to polynomials in Z of the form n a n Z n (except for f 13 ) and compared with theoretical and with earlier fitted values.
