AI Article Synopsis
- An ion-momentum spectrometer analyzes how molecules break apart when they attach to electrons.
- A supersonic gas jet combined with a pulsed low-energy electron beam allows for the creation of negative ions.
- Momentum calculations in three dimensions reveal both the angular dependence of this process and the energy changes involved in the reactions.
Article Abstract
An ion-momentum spectrometer is used to study the dissociative dynamics of electron attachment to molecules. A skimmed, supersonic gas jet is crossed with a pulsed beam of low-energy electrons, and the resulting negative ions are extracted toward a time- and position-sensitive detector. Calculations of the momentum in three dimensions may be used to determine the angular dependence of dissociative attachment as well as the energetics of the reaction.
