Article scientifique
Absolute 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 ...
Ionisation et dissociation d’ions moléculaires par impact électronique![Peer reviewed Peer reviewed](/themes/Mirage2//images/peer_review.svg)
Livre/Ouvrage ou monographie
Les processus de collisions atomiques et moléculaires sont étudiés expérimentalement à Louvain-la-Neuve (UCL, Belgique). Les phénomènes considérés sont de première importance en physique des plasmas de fusion contrôlée. Le développement actuel du projet de réacteur nucléaire ITER (International Thermonuclear Experimental Reactor, Cadarache, France) implique spécialement un besoin toujours accru de ...
Spectroscopy and dynamics of the 7,7,8,8-tetracyanoquinodimethaneradical anion![Peer reviewed Peer reviewed](/themes/Mirage2//images/peer_review.svg)
Article scientifique
The photoelectron spectrum of the 7,7,8,8-tetracyanoquinodimethane (TCNQ) radical anion has
been measured at 3.1 eV. Additionally, the ultrafast relaxation dynamics of the first excited state
(12B3u) of TCNQ have been studied using time-resolved photoelectron spectroscopy, which
reveals that it undergoes internal conversion back to the ground state (2B2g) with an associated
lifetime of 650 fs ...
III. Electron-impact dissociative ionization of C2H +2 and C2D +2![Peer reviewed Peer reviewed](/themes/Mirage2//images/peer_review.svg)

Article scientifique
Absolute cross-sections for electron-impact dissociative ionization of C2 H +2 and C2 D +2 to CH+, C+, C +2 , H+, CH +2 and C2D+ fragments are determined for electron energies ranging from the corresponding threshold to 2.5 keV. Results obtained in a crossed beams experiment are analyzed to estimate the contribution of dissociative ionization to each fragment formation. The dissociative ionization ...

Article scientifique
Absolute cross-sections for electron-impact dissociative excitation of C2H +2 and C2D +2 to C2D+, CH+, C+, C +2, H+ and CH +2 singly-charged fragments have been estimated. The animated crossed-beams method is applied in the energy range from the corresponding reaction threshold up to 2.5 keV. Individual contributions for dissociative excitation are determined from the analysis of the total absolute ...
