Abstract

Absolute cross sections for electron-impact single and multiple ionization of Ne+ leading to the formation of Neq+ (q = 2–5) are reported. The animated crossed beams method is applied in the energy range from the respective thresholds up to 2.5 keV. The maximum cross sections are found to be (4.12 ± 0.21) × 10−17 cm2, (1.42 ± 0.07) × 1018 cm2, (2.57 ± 0.14) × 10−20 cm2, (8.78 ± 0.54) × 10−22 cm2 for the multiply-charged products Neq+ (q = 2–5), respectively. The corresponding threshold energies are measured to be (41.0 ± 0.5) eV, (105 ± 1) eV, (205 ± 5) eV and (345 ± 15) eV. Present data are compared with available experimental and theoretical results.
