L sub-shell fluorescence cross-section measurements for elements, Z = 62–67, at tuned photon energies

Measurement of L subshell fluorescence yield ratios of some high Z elements by selective excitation method

“…Several investigators have measured the L X-ray intensity ratios, L subshell fluorescence yield and Coster-Kronig transition parameters by exciting the target with gamma radiation, charged particles and synchrotron radiation. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Singh et al [4] have measured average L shell fluorescence yields for some elements in the range 56 ≤ Z ≤ 92. Ertugrul et al [5] have measured average 2p subshells fluorescence yields for the elements 60 ≤ Z ≤ 90.…”

“…Sahnoune et al [13] reviewed the existing L shell fluorescence yields published in the period 1954-2015 and deduced an empirical average L shell fluorescence yields for the elements in the atomic number from 23 to 96. Bansal et al [14] have determined L subshell fluorescence cross-sections for Z = 62-67 at tuned photon energies. Using monochromatic synchrotron radiation, the photoionization of individual subshells can be initiated and consequently the Coster-Kronig and L subshell fluorescence yields can be determined accurately.…”
