| Abstract: | 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. The maximum total cross sections for O+ and D+ fragments production are observed to be (15.7? ± ?0.2) × 10?17 cm2 at 95 eV and (10.8? ± ?0.5) × 10?17 cm2 at 95 eV, respectively. The cross sections for O2+ and O3+ are much smaller, (5.37? ± ?0.04) × 10-18 cm2 at 135 eV and (7.95? ± ? 0.23) × 10-20 cm2 at 315 eV, respectively. The collected data are analyzed in details in order to determine separately the contributions of dissociative excitation and of dissociative ionization to the O+ and D+ fragments production. |
