Electron-induced vibrational excitation of CO_{2} in dc electric and magnetic fields

Abstract

In the present study rate coefficients for vibrational excitation of CO_{2} gas molecules by electrons in the presence of uniform electric and magnetic fields are investigated. Calculations are performed for transition from the ground state to each of the symmetric, asymmetric, and bending vibrational states. A Monte Carlo simulation is used to produce nonequilibrium electron energy distribution functions. Results are obtained for the electric field over gas number density ratio, E/N, ranging from 20 to 1000 Td, and for the magnetic field over gas number density ratio, B/N, with values of 0, 1000, 2000, and 3000 Hx.
