Measurement of L3 subshell absorption edge parameters in the elements of lanthanide series (Z=57–70)

The excitation probabilities of Kα,β and Lα1,2 for some elements in 56≤Z≤68 at 59.54keV

“…There are four different ways to determine the absorption jump ratio and jump factor. The first method is the energy dispersive X-ray fluorescence (EDXRF) method (Ertuğrul et al, 2002;Budak et al, 2003;Bennal and Badiger, 2007;Kaya et al, 2008a;Kahlon et al, 2011;Sidhu et al, 2011a;Kaya et al, 2011;Sidhu et al, 2011b;Kaçal, 2014;Gupta et al, 2014;Cengiz and Sarıtaş, 2014;Akman et al, 2015;Kaçal et al, 2015) based on determination of fluorescence parameters such as the production cross section, fluorescence yield, intensity ratio, total atomic absorption and scattering cross section. The second method is the X or gamma ray attenuation method (Polat et al, 2005;Kaya et al, 2007;Kaya et al, 2008b;Niranjana et al, (2013); Cengiz et al, 2013).…”

Measurement of absorption edge parameters near K edge for the compounds of Zn, Zr, Cd, Ba and Pb

“…Ratio of the values of photoelectric absorption coefficient on higher energy to lower energy side at an edge directly gives its absorption jump ratio and difference in the values of photoelectric absorption coefficient on both sides of an edge gives photoelectric cross-section of particular shell/ sub shell. Further, work on jump factor and jump ratios for K shell and L shell/subshell for the pure elements is also carried out by some researchers [18][19][20][21][22][23][24]. But the measurements related to absorption edge parameters i.e.…”
