Abstract

A simple modification of the Vaisburd and Evdokimov model (VE) [Russ. Phys. J. 46, 1160 (2003)], with a acronym MVE, embodying the relativistic effects is proposed and employed to evaluate the K-shell ionization cross sections of atomic targets with atomic numbers 6 ≤ Z ≤ 92 for incident energies EThreshold ≤ E ≤ 10 GeV. For a meaningful comparison we also revisited our earlier MUIBED model [Int. J. Q. Chemistry, 108, 1023 (2008)] to obtain the K-shell ionization cross sections for 24 atomic targets and above mention energy range. It is found that our new results from the MVE model agrees quite well not only with available experimental data but also with other theoretical values.
