Sequential over-barrier ionization of multi-electron atoms in the tens-to-hundreds keV/u energy range

doi:10.1088/1674-1056/21/3/033401

Abstract Our previous work on the classical over-barrier ionization model for helium double ionization is extended to the complex multi-electron system of Ne. The total and q-fold ionization cross sections are calculated at energies ranging from a few tens to several hundred keV/u. The calculation results are in good agreement with the experimental data, and the energy dependence of the cross sections suggests that the multi-ionization of a strong perturbated complex atom is probably the sequential over-barrier ionization process.
