The LIII subshell photoelectric cross section, jump ratio, jump factor, and Davisson–Kirchner ratio of iridium have been determined by mass attenuation coefficients. The measurements have been performed using the X-ray attenuation method in narrow beam geometry. The obtained results have been compared with the tabulated values of XCOM (Berger et al. XCOM: Photon cross section database (version 1.3). NIST. Available at http://physics.nist.gov/xcom . 2005) and FFAST (Chantler et al. X-ray form factor, attenuation and scattering tables (version 2.1). NIST. Available at http://physics.nist.gov/ffast . 2005).

AbstractMass attenuation coefficients (MACs) of Th, U, Np, and Pu for oxygen X-rays have been experimentally determined using an electron microprobe. The MACs were obtained by measuring relative X-ray intensities emitted from ThO2, UO2, NpO2, and PuO2 targets, for incident electron energies from 5 to 30 keV, and processing them with the help of the computer program XMAC. The accuracy of the measured MACs is estimated to be better than 5%. Results are compared with MAC tabulations commonly used in electron probe microanalysis as well as with theoretical photoionization calculations. It is concluded that the MACs implemented in the Monte Carlo simulation program PENELOPE which are based on the photoionization cross-section calculations of Sabbatucci & Salvat [(2016). Theory and calculation of the atomic photoeffect. Rad Phys Chem121, 122–140], provide the best agreement with our measurements. The use of different MAC schemes for the analysis of mixed actinide oxide materials is discussed.

In this study the value of linear  and mass  attenuation coefficients of Aluminum element (Al) were determinated by using x-ray Cu-tube of energies CuKα (8.048) KeV, CuKβ (8.906) KeV, and Mo-tube of energies MoKα (17.480) KeV and MoKβ (19.609) KeV.the voltage between the two electrodes are up to 35 KV.The measured  values are compared with other experimental data showing a general agreement within a precision of 0.2% - 0.8%. The mass attenuation cross-sections were thus derived and compared with other experimental data available on database of x-ray attenuation cross-sections. The agreement is always within ±7%.   http://dx.doi.org/10.25130/tjps.24.2019.013
