Measurement ofK ?cross sections and fluorescence yields for elements in the range 42?Z?57 using radioisotope X-ray fluorescence

K-shell fluorescence yields for elements with 6≤Z≤99

“…The K-shell fluorescence yield of an atom is defined as the probability that a vacancy in the K-shell is filled through a radiative transition. Several attempts have been made, in a tabular form, for measuring (Al-Nasr et al, 1987;Arora et al, 1981;Ahmad, 1979;Broyles et al, 1953;Bertrand et al, 1959;Bambynek et al, 1965;Brabets et al, 1959;Balakrishna et al, 1994;Brunner, 1987;Bhan et al, 1981;Famoux, 1985;Casnati et al, 1991;Chen et al, 1979;Drever and Moljk, 1957;Durak and Sahin, 1998;Erman and Sujkowski, 1961;Espenschied and Hoffmann, 1978;Egorov et al, 1989;Fairbrother et al, 1957;Forest and Easterda, 1959;Freedman et al, 1977;Frey et al, 1958;Garg et al, 1985;Godeau, 1961;Gray, 1956;Graham and Merritt, 1961;Apaydın and Tıras -oglu, 2006;Geidelman et al, 1988;Gurov et al, 1981;Harrison et al, 1955;Han et al, 2007;Heintze, 1955;Hagedoorn and Konijn, 1957;Hagedoorn and Wapstra, 1960;Hoffman and Dropesky, 1958;Hribar et al, 1977;Konstantinov et al, 1961;Kramer et al, 1962;Kramer, 1961;Konstantinov et al, 196...…”

Measurement ofKx-ray emission from Mo, Cd, and Sn stimulated by 59.54-keV photons

“…The a and P fiuorescence cross sections of Garg et al [17] have simply been summed to one another and expressed in barns. Al-Nasr et al [18] give the a Auorescence cross section which, when expressed in barns, gives co&~& immediately by multiplying it by 1+R, R being the above-mentioned ratio p jp& for which the Scofield [4,21] values were used. Sn, including the ones obtained in the present work and those of the mentioned authors as well as the product of Hubbell's co& (Ref.…”

“…54 keV, respectively, by means of a Si(Li) spectrometer. Al-Nasr et al [18] measured the same quantity at 59.54-keV photon energy for eight elements in the 42~Z 57 range with a Ge detector.…”

X-ray fluorescence in some rare earth and high Z elements excited by 661.6 keV γ-rays

“…Later, in 1984, Bambynek et al [9] in their review article presented a further re-evaluation of ω K values incorporating new measurements. Some measurements of K-XRF cross sections for low and medium Z elements at low excitation energies have been reported (see [10][11][12][13][14][15][16]). Several measurements of K as well as higher shell fluorescence yields have been reported [17,18].…”
