Calculation of M x‐ray production cross sections from 1–1500 keV in the atomic region 70 ⩽ Z ⩽ 92

Abstract

M x‐ray production cross sections from 1 to 1500 keV were obtained for elements with 70 ⩽ Z ⩽ 92. Obtained values were tabulated and plotted against the atomic number and energy. In the calculation process, published sources were used. The radiative transition rates and photoionization cross sections of the elements were taken from the relativistic Hartree‐Slater model of Scofield (At. Data Nucl. Data Tab. 14, 121 (1974), UCRL‐51376 (1973)), the nonradiative transition rates were taken from the Dirac‐Hartree‐Slater model of Chen et al. (At. Data. Nucl. Data Tab. 24, 14(1979)) and average M shell fluorescence yield values were obtained from Hubbell et al. (J. Phys. Chem. Ref. Data 23, 339 (1994)). Copyright © 2004 John Wiley & Sons, Ltd.

M shell Fluorescence Parameters of Pt, Au and Tl Compounds with Oxygen and Bromide

“…It is known that M X-ray fluorescence parameters are essential for many applications apart from the atomic physics studies including the surface chemical analysis, dosimetric computations for health physics, cancer therapy and industrial irradiation processing [6]. In the literature, M shell fluorescence parameters were investigated by using different methods or different calculation procedures at different photon energies.…”
