Vibrational excitation of water by electron impact
نویسندگان
چکیده
Experimental and calculated differential cross sections DCSs for electron-impact excitation of the 010 bending mode and unresolved 100 symmetric and 001 antisymmetric stretching modes of water are presented. Measurements are reported at incident energies of 1–100 eV and scattering angles of 10° –130° and are normalized to the elastic-scattering DCSs for water determined earlier by our group. The calculated cross sections are obtained in the adiabatic approximation from fixed-nuclei, electronically elastic scattering calculations using the Schwinger multichannel method. The present results are compared to available experimental and theoretical data.

Systematic comparison of positron - and electron - impact excitation of the 3 vibrational mode of CF
Absolute measurements are presented for the excitation of the 3 vibrational mode in CF4 by positron and electron impact from 0.1 to 2 eV. To minimize systematic differences, these measurements were made using the same trap-based electron or positron beam, associated experimental apparatus, and procedures. Unlike other vibrational excitation cross sections studied to date, the near-threshold cro...
متن کاملElectron-impact resonant vibrational excitation and dissociation processes involving vibrationally excited N2 molecules
Resonant vibrational excitation cross sections and the corresponding rate coefficients for electron–N2 collisions occurring through the N − 2 (X 2 g) resonant state are reviewed. New calculations are performed using accurate potential energy curves for the N2 electronic ground state, taken from the literature, and for the N2 resonant state, obtained from R-matrix calculations. The calculations ...
متن کاملCalculation of rate constants for vibrational and rotational excitation of the H3 ion by electron impact
We present theoretical thermally averaged rate constants for vibrational and rotational (de-)excitation of the H3 ion by electron impact. The constants are calculated using the multichannel quantum-defect approach. The calculation includes processes that involve a change | J | ≤ 2 in the rotational angular momentum J of H3 . The rate constants are calculated for states with J ≤ 5 for rotational...

Wadehra JM, Drallos PJ. Simple model for the resonant vibrational excitation of molecules and its application to Li2 and N2. Phys. A simple model for the resonant vibrational excitation of a molecule by electron impact is proposed in which the potential curves of the electronic states of the molecule and its resonant anion are replaced by those of linear harmonic oscillators of arbitrary freque...
