K and L Shell X-Ray Fluorescence Cross Sections

Measurements of Lα, Lβ X-ray production cross sections of Bi by 17–40keV electron impact

“…In Eqs. (4) and (5), when the incident electron energies are larger than the K-shell ionization threshold energies, the vacancy transfers from the K-shell to L subshells should be taken into account [29][30][31]. Finally, the K factors can be obtained using the following Eq.…”

Li (i=1–3) subshell X-ray production cross sections and fluorescence yields for some elements with 56⩽Z⩽68 at 22.6keV

“…The details are given elsewhere [15,20]. In these calculations, the theoretical values of the K XRP cross sections were taken from reference [21]. The I o Ge values for the present setup are plotted as a function of energy in Fig.…”

Rayleigh, Compton and K-shell radiative resonant Raman scattering in 83Bi for 88.034keV γ-rays

“…The I 0 Ge values were determined over the energy-region 42.8-85.4 keV by measuring the K X-rays from the Gd, Dy, Ho, Er, Yb, Ta, W, Pt, Au, Hg, Tl and Pb targets excited by the incident 88.034 keV c-rays and using the K X-ray fluorescence cross-sections at the 88.034 keV energy interpolated from the tables given by Puri et al [20]. The relative efficiency of the detector over the energy region 42.8-105.0 keV was also determined in the same geometrical set up by placing calibrated mixed standard ( 125 Sb, 154 Eu and 155 Eu), 155 Eu, 166 m Ho, 133 Ba and 241 Am radioactive sources at the target position after removing the 109 Cd source.…”
