“…The discrepancy in the lower energy range likely arises from omitting the excitation-autoionization contributions [54][55][56] in the present model. The difference between the present computations and experiment mainly arise from autoionization contributions due to the excitation of the 5p and 5s electrons into autoionization states with thresholds (12.256 46 and 20.9515 eV for the 5p and 5s electrons, respectively [57,58]) near the corresponding ionization potentials of each orbital.…”

A generalized binary-encounter-Bethe (GBEB) model is proposed to calculate the partial ionization cross sections of all shells. The present model improves the original version of Kim \textit{et al.} [Phys. Rev. A \textbf{62}, 052710 (2000)] by incorporating a physically constructed effective charge felt by the ejected electron in the empirical factor, which prevents the selection of specific factors for different shells. A generalized relativistic BEB formula is also proposed and applied to different inner shells of C, Al, Fe, Ar, Ag, Xe, Sn, Pb, and Bi atoms for impact energies from the thresholds up to $10^{6}$ keV. The present model improves the partial ionization cross sections in the low-energy region compared to other relativistic BEB models. The GBEB partial and total ionization cross sections of the Xe atom are compared with the original BEB results. The present calculations, combined with the contribution from the direct multiple ionization, show good agreement with the experimental measurements in the intermediate- and high-energy ranges. We conclude that the present GBEB model, without any fitting parameters and \textit{ad hoc} corrections, improves the BEB prediction of partial and total ionization cross sections for a good variety of atomic targets.

“…Similarly to what has been done in recent work by others [32,33] we take only indirect ionization processes into account. In particular, we consider ionization-autoionization (IA) and excitation doubleautoionization (EDA), which are the dominant contributions to EIDI of heavy many-electron ions.…”

We present new experimental and theoretical cross sections for electron-impact single ionization of Xe$$^{12+}$$ 12 + and Xe$$^{13+}$$ 13 + ions, and double ionization of Xe$$^{12+}$$ 12 + , Xe$$^{13+}$$ 13 + and Xe$$^{14+}$$ 14 + ions for collision energies from the respective ionization thresholds up to 3500 eV. The calculations use the fully relativistic subconfiguration-averaged distorted-wave approach and, partly, the more detailed level-to-level distorted wave method. We find that, unlike in previous work, our theoretical cross sections agree with our experimental ones within the experimental uncertainties, except for the near-threshold double-ionization cross sections. We attribute this remaining discrepancy to the neglect of direct-double ionization in the present theoretical treatment.
