Absolute cross sections and kinetic energy release distributions for electron impact ionization and dissociation of CD+
2007, LECOINTRE, Julien; Cherkani-Hassani, S.; Belic, D. S.; Jureta, J. J.; Becker, K.; Deutsch, H.; Märk, T. D.; Probst, M.; Janev, R. K., HENALLUXArticle scientifiqueAbsolute cross sections for electron impact dissociative excitation and ionization of CD+ leading to the formation of ionic products (D+, C+, C2+ and C3+) are reported in the energy range from their respective thresholds to 2.5 keV. Around the maximum, cross sections are found to be (10.5 ± 1.0) × 10−17 cm2, (20.6 ± 3.5) × 10−17 cm2, (1.20 ± 0.11) × 10−17 cm2 and (8.2 ± 1.5) × 10−20 cm2 for D+, C+, ... -
Electron impact dissociation of ND+: formation of D+
Article scientifiqueAbsolute cross sections for electron impact dissociation of ND+ leading to the formation of D+ have been measured by applying the animated electron-ion beam method in the energy range from the reaction threshold up to 2.5 keV. The maximum inclusive cross section is observed to be (16.8 ± 0.8) × 10−17 cm2 at the electron energy of 65.1 eV. The appearance energy for the D+ production is measured to ... -

2012, LECOINTRE, Julien; Belic, D. S.; Jureta, J. J.; Cherkani-Hassani, H.; Cherkani-Hassani, S.; Defrance, P., HENALLUXArticle scientifiqueAbsolute 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. ... -
Electron-impact ionization and dissociation of C2D+
2010, LECOINTRE, Julien; Cherkani-Hassani, H.; Cherkani-Hassani, S.; Belic, D. S.; Jureta, J. J.; Defrance, P., HENALLUXArticle scientifiqueAbsolute 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 ... -
I. Electron-impact ionization and dissociation of C2H +2 and C2D +2
2010, LECOINTRE, Julien; Cherkani-Hassani, H.; Cherkani-Hassani, S.; Belic, D. S.; Jureta, J. J.; Defrance, P., HENALLUXArticle scientifiqueAbsolute 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 ...
