| Popis: | Single electron capture from molecular uracil (C4H4N2O2) by doubly-charged He2+, C2+, and O2+ atomic ions followed by the fragmentation of uracil ions has been studied using time-of-flight mass-spectrometry at the collision velocity range 0.13–0.65 a.u. The uracil ion fragmentation mechanism has been clarified by the arrival time correlation analysis for all ion-fragments produced in a single collision. Electron capture with ionization cross section has been determined from experiment. As shown, single electron capture in reaction of uracil with C2+ leads to high fragmentation probability of the resulting uracil ion. The role of electron core rearrangement in the C2+ and O2+ atomic ions is discussed. |
