X Ray ◽

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

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).

The total mass attenuation coefficients (μt) (cm2/g) and atomic, molecular, and electronic effective cross sections have been calculated for nonessential amino acids that contain H, C, N, and O such as tyrosine, aspartate, glutamine, alanine, asparagine, aspartic acid, cysteine, and glycine in the wide energy region 0.015–15 MeV. The variations with energy of total mass attenuation coefficients and atomic, molecular, and electronic cross sections are shown for all photon interactions.
