نویسندگان
چکیده
Cross-sections and thermally averaged rate coefficients for vibration (de-)excitation of a water molecule by electron impact are computed; one two quanta excitations considered all three normal modes. The calculations use theoretical approach that combines the mode approximation vibrational states water, frame transformation employed to evaluate scattering matrix transitions UK molecular R-matrix code. interval applicability is from 10 10,000 K. A comprehensive set performed assess uncertainty obtained data. results should help in modelling non-LTE spectra various astrophysical environments.

متن کاملElectron-impact resonant vibration excitation cross sections and rate coefficients for carbon monoxide
Resonant vibrational and rotation–vibration excitation cross sections for electron–CO scattering are calculated in the 0–10 eV energy range for all 81 vibrational states of CO, assuming that the excitation occurs via the 2 shape resonance. Static exchange plus polarization calculations performed using the R-matrix method are used to estimate resonance positions and widths as functions of intern...
متن کاملResonant vibrational-excitation cross sections and rate constants for low-energy electron scattering by molecular oxygen
Resonant vibrational-excitation cross sections and rate constants for electron scattering by molecular oxygen are presented. Transitions between all 42 vibrational levels of O 2 (X 3 − g) are considered. Molecular rotations are parametrized by the rotational quantum number J , which is considered in the range 1–151. The lowest four resonant states of O − 2 , 2 g , 2 u , 4 − u and 2 − u are take...
متن کاملIntermediate energy cross sections for electron-impact vibrational-excitation of pyrimidine.
We report differential cross sections (DCSs) and integral cross sections (ICSs) for electron-impact vibrational-excitation of pyrimidine, at incident electron energies in the range 15-50 eV. The scattered electron angular range for the DCS measurements was 15°-90°. The measurements at the DCS-level are the first to be reported for vibrational-excitation in pyrimidine via electron impact, while ...
