Cross sections for production of O$sub 2$$sup -$ and C$sup -$ by dissociative electron attachment in CO$sub 2$: an observation of the Renner-Teller effect
Using monoenergetic electron beams and mass analysis, we have measured the cross sections for production of O-/sub 2/ and C- by dissociative attachment in CO/sub 2/. The cross section for O-/sub 2/ production has two peak s of the order of 10/sup -24/ cm/sup 2/ at 11.3 plus or minus 0.2 and 12.9 plus or minus 0.2 eV incide nt on energy. The double peaked nature of the cross section is interpreted as a manifestation of the Renner-Teller effect. The positions of these two peaks are in good agreement with INDO calculations. The cross section for C- production has three peaks at 16.0 plus or minus 0.2, 17.O plus or minus 0.2, and 18.7 plus or minus 0.1 eV, the largest of which, at 18.7 eV, has magnitude of approximately 2 x 1O/sup -21/ cm/sup 2./ (auth)
