摘要/Abstract

摘要： The values of cross-section ratio R_k1 of direct k-fold ionization cross section (σ_k) to direct single ionization cross section (σ₁) of Ne impacted by C^q+ (q=1–3) ions in an energy range of 10 keV/u–500 keV/u are measured in this work. The experimental data are compared with the results from our multi-electron classical over-barrier ionization (ME-COBI) model, showing that the model can give a good estimate to the experimental data.
