摘要：

We present new experimental and theoretical cross sections for electron-impact single ionization of Xe(12+)and Xe(13+)ions, and double ionization of Xe12+,Xe(13+)and Xe(14+)ions for collision energies from the respective ionization thresholds up to 3500 eV. The calculations use the fully relativisticsubconfiguration-averaged distorted-wave approach and, partly, the more detailed level-to-level distortedwave method. We find that, unlike in previous work, our theoretical cross sections agree with our exper-imental ones within the experimental uncertainties, except for the near-threshold double-ionization crosssections. We attribute this remaining discrepancy to the neglect of direct-double ionization in the presenttheoretical treatment
