摘要: Theoretical studies of electron impact double ionization cross sections of Ne5+ and Ne6+ ions have been performed in the binary encounter approximation (BEA). Direct (DDI) has investigated modified double encounter model. The K-shell also calculated BEA to take into account contributions from the ionization-autoionization (IA) process. effect Coulombic field target ion on incident considered present work. Accurate expression of σ ΔE (cross section for energy transfer ΔE) Hartree-Fock (HF) velocity distributions target electrons used throughout calculations. results are overall moderate agreement with experimental observations. Possible reasons behind the discrepancies between theory experiment discussed.
