摘要：
The calculation of rate constants and branching ratios was carried out to study the dissociative recombination of CO 2 +. The recombination of CO 2 + is significant in the atmospheres of Venus and Mars. Rate constants and cross sections were studied by ramping the electron beam around a center-of-mass energy of 0 eV. The results of the study confirms that all the recombination of CO 2 + results in a simple bondbreaking to form CO plus O. The rate constants show good agreement with measurements at 300 K and the electron energy dependence is identical to storage ring results.
