Relativistic calculations of K-, L- and M-shell X-ray production cross-sections by electron impact for Ne, Ar, Kr, Xe, Rn and Uuo

•X-ray production cross-sections are calculated for several noble elements.•Electron-Impact Ionization cross-sections are computed with the MRBEB model.•Binding energies and atomic yields are obtained with the Dirac-Fock approach.•Comparisons are made with other theoretical models and few available data.•This approach is reliable in producing X-ray production cross-section data.

In this work, we derive X-ray production cross-sections from electron-impact ionization cross-sections for Ne, Ar, Kr, Xe, Rn, and Uuo, calculated in the modified relativistic binary-encounter-Bethe model, and using as the only input parameter the binding energies obtained in the Dirac-Fock approach. Radiative and radiationless transition probabilities necessary to compute the inter- and intra-shell atomic yields were calculated in the same approach. Shell electron-impact ionization cross-sections and X-ray production cross-sections are compared with the corresponding cross-sections retrieved from the National Institute of Standards and Technology Reference Database and available experimental data.
