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

摘要

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.
