Measurement of photon-induced L X-ray production cross-sections for some elements with 40 ≤ Z ≤ 70 at 122 keV

Kβ/Kα X-Ray Intensity Ratios for Cr, Mn, Fe, and Co Excited by 8.735 keV Energy

“…The theoretical values of K X-ray production crosssections σ Kα and σ Kβ have been calculated using the following equations [23]:…”

“…Our earlier study is related to measurements of K-shell X-ray production cross-sections and fluorescence yields for some elements in the atomic number range 28 ≤ Z ≤ 40 using secondary method [22]. K shell X-ray fluorescence cross-sections have been measured for some elements [23][24][25]. Özdemir et al have investigated K X-ray intensity ratios of some 4d transition metals depending on the temperature [26].…”

Kβ/Kα X-ray intensity ratios for some elements in the atomic number range 28≤Z≤39 at 16.896 keV

“…The measurements of K b =K a intensity ratios are important for comparison with theoretical predictions based on atomic models in order to test the validity of these models. This ratio is also important as it may be used to determine the L/K electronic capture ratio and fluorescence yield of the L-shell (Ertu grul, S€ o güt, Ş imş ek, & Büyükkasap, 2001).…”

“…Baydaş , Ş ahin, and Büyükkasap (2003) have measured K a and K b X-ray fluorescence cross sections and the K b =K a intensity ratios for elements in the range 22 Z 29 by 10 keV photons using a secondary excitation method. Ertu grul et al (2001) have measured the K b =K a intensity ratios for elements in the range 22 Z 69 at 59.5 keV. Ertu grul and Ş imş ek (2002) have measured K X-ray relative intensities of Tm, Yb, Lu, Ta, W, Re, Au, Hg, Tl, Pb, Bi, Th and U elements.…”

“…My earlier the study of K shell fluorescence cross-sections has included measurements for Cr, Fe, Mn and Co elements at low energy using secondary method (Yılmaz, R., 2014). K shell X-ray fluorescence cross-sections have been measured for some elements (Durak, Erzeno glu, Kurucu, & Ş ahin, 1998;Karabulut, Budak, Demir, & Ş ahin, 1999;€ Ozdemir, Durak, & € Oz, 2002). In this work, we report the measurements of K a and K b X-ray production cross-sections and the K b =K a X-ray intensity ratios for some elements in the range 28 Z 39 The targets have been excited with 16.896 keV photons using secondary excitation method.…”
