Absolute cross-sections for electron-impact ionization and dissociation of C2H +2 and C2D +2 have been measured for electron energies ranging from the corresponding thresholds up to 2.5 keV. The animated crossed beams experiment has been used. Light as well as heavy fragment ions that are produced from the ionization and the dissociation of the target have been detected for the first time. The maximum ...

Absolute cross sections for electron-impact single ionization, dissociative excitation and dissociative ionization of the ethynyl radical ion (C2D+) have been measured for electron energies ranging from the corresponding reaction thresholds to 2.5 keV. The animated crossed electron-ion beam experiment is used and results have been obtained for the production of C2D2+, C2+, C+2, CD+, C+ and D+. The ...

Absolute cross sections for electron impact ionization and dissociation of OH+ and OD+ leading
to the formation of the OH2+, O+, O2+, O3+ and D+ ions have been measured by applying the animated
electron-ion beam method in the energy range from the respective reaction thresholds up to 2.5 keV. The
maximum of the single ionization cross section is found to be (0.95±0.02) × 10−19 cm2 at 155 eV. ...

Absolute cross sections for electron impact single and multiple ionization of argon ions
leading to the formation of Ar q + (q = 2–8) are reported. The animated crossed beam method
is applied in the energy range extending from the respective thresholds up to 2.5 keV. The
maximum cross sections for the multiply charged products Ar q + (q = 2–8) are measured to be
(12.6 ± 0.6) × 10−17 cm2 for Ar2+, ...
