Non-conservative and electronic excitation rates of CO2 in DC electric field

The topic of this research is the rate coefficient calculations for the formation of the CO2 molecule ions and their fragments resulting from collisions between electrons and the CO2 gas molecules in the presence of a homogeneous external electric field. The rate coefficients for electronic excitations, which are simultaneously occurring in those conditions, are also calculated. In order to obtain the non-equilibrium electron energy distribution functions (EEDFs) in the CO2 gas in the presence of a homogeneous DC electric field, we have used the Monte Carlo simulation method. The rate calculations have been performed by integration of cross sections for the mentioned processes for EEDFs obtained by simulation. The rates were calculated and presented for reduced electric field values, E/N, in the range from 20 to 1000 Td.
