We report an extension and modification of the MCN model of Haque et al (2013 Rad. Phys. Chem. 91 50-9) (XMCN) to study the electron impact ionization of inner L and M shells of neutral atoms by introducing new parameters of the MCN model. The extended XMCN model, including the relativistic effect, has been applied with success to evaluate ionization cross-sections of various atomic targets with Z = 38-92 for both individual subshells and total L-shell and the corresponding cross-sections for the M shell for Z = 79-92 at incident energies E Threshold ≪ T ≪ 1 GeV. A comparison with other available theoretical and experimental cross-sections reveals that our results reproduce the experimental measurements with a reasonable accuracy.
