Abstract

The main objective of this paper is to calculate semi-theoretical values for the L-shell X-ray intensity ratios

I_{L i} / I_{L α}

(i =

β

and γ) across a broad range of elements in the atomic number range 36 ≤ Z ≤ 92 and photon excitation energies spanning from 1.916 keV to 200 keV. These values are derived from theoretical calculations and subsequently refined using an advanced interpolation approach based on a three-dimensional function incorporating atomic number Z and excitation energy E. The dependence of the L-shell intensity ratios on the incident photon energy is analyzed, highlighting variations across different elements. A comparison was carried out for selected excitation energies of 22.6 keV and 59.54 keV, integrating weighted average values, theoretical calculation, and experimental data from the literature to evaluate their reliability and accuracy.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
