Title: | Resonant vibrational excitation and De-excitation of CO(v) by low energy electrons | Authors: | Poparić, Goran Ristić, M. Belić, D. S. |
Issue Date: | 4-Dec-2008 | Journal: | Journal of Physical Chemistry A | Abstract: | Integral cross sections and rate coefficients for vibrational excitation of the excited carbon-monoxide molecule, via the 2∏ shape resonance in the energy region from 0 to 5 eV have been calculated. Cross sections are calculated by using our recently measured cross sections for the ground level CO excitation and the most recent cross sections for elastic electron scattering, applying the principle of detailed balance. Rate coefficients are calculated for Maxwellian electron energy distribution, with mean electron energies below 5 eV. By using extended Monte Carlo simulations, electron energy distribution functions (EEDF) and rate coefficients are determined in nonequilibrium conditions, in the presence of homogeneous external electric field. Nonequilibrium rates are calculated for typical, moderate values of the electric field over gas number density ratios, EIN, from 1 to 220 Td. Maxwellian and nonequilibrium rate coefficients are compared and the difference is attributed to a specific shape of the electron energy distribution functions under considered conditions. © 2008 American Chemical Society. |
