Semiempirical analysis of electron scattering cross sections in N2O and CO2
Tóm tắt
Results of swarm analysis of electron scattering cross sections in nitrous oxide and carbon dioxide are presented — experimental diffusion coefficients are compared with numerical solution of the Boltzmann equation. Total cross sections for both N2O and CO2 exhibit similar resonant, structure and diffusion and drift coefficients are also similar. However, our analysis shows that values of partial cross sections, in particular vibrational ones (important for greenhouse IR absorption) can be quite different for those gases at low energies — much higher that commonly used now.
