Renner-Teller Effect on Dissociative Electron Attachments to Carbon   Dioxide
  Stereo-dynamics of dissociative electron attachments to CO_2 is investigated by the O^- anion velocity imaging experiments combined with the R-matrix calculations. ^2{\Pi}_g as a Feshbach resonant state of CO_2^- is confirmed to play roles in the dissociations around 8.0 eV. We find that the dynamic evolutions of the Renner-Teller effect lead to the dramatically different anisotropic O^- momentum distributions.
