Measurement of theL2-L3Coster-Kronig transition probability in Pb (Z=82)

Measurement of Coster-Kronig and fluorescence yields of the L2and L3subshells of heavy atoms

“…This work provides several results (spanning 72 S 2 G 82) in graphic form but the only numerical datum quoted is that for Z = 8 2 , which we include in figure 8; it lies well below the trend of our results. The new work of Catz, who also applied an x-ray coincidence technique to the radionuclide 207Bi, produced a result of 0.112*0.001 (Catz 1987), in excellent agreement with our result. Consequently, this may be the first evidence of a dependence of Coster-Kronig transition probabilities upon the mechanism that creates the initial L vacancy, a speculation which merits examination experimentally and theoretically.…”

Measurement of atomic L shell Coster-Kronig yields (f12,f23andf13) for some elements in the atomic number range 59⩽Z⩽90

“…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].…”

X-ray fluorescence activities at Saha Institute of Nuclear Physics, India

“…In single spectrum method, the precision of the measurements cannot be brought down below a few percent while in the latter, it can be brought down even less than 1%. In coincidence experiments [7][8][9][10], radioactive targets are used but for all elements, it is difficult to get the longlived radioactive targets. The alternative way will be to excite a sample with a suitable radioactive source whose excitation energy is very close to the K shell binding energy of the element.…”
