Abstract

A Velocity Slice Imaging (VSI) study on Dissociative Electron Attachment (DEA) to carbon tetrafluoride, CF₄, is presented. Two fragments are observed; F⁻ produced from two, partly overlapping, resonances and CF₃^- deriving from a single resonance. The angular distributions of these anionic fragments and their kinetic energy distributions are reported and are then discussed in context of the influence of the Jahn-Teller effect on the symmetry of the resonant states involved.
