We present an improved nonlocal resonance model for electron-HCl collisions. The short-range part of the model is based on ab-initio electron scattering eigenphase sums calculated using the Schwinger Multichannel method and the long-range part on the potential curve of the bound HCl⁻ anion. We have calculated cross sections for vibrational excitation and dissociative electron attachment.... Plus

    Summary
    We present an improved nonlocal resonance model for electron-HCl collisions. The short-range part of the model is based on ab-initio electron scattering eigenphase sums calculated using the Schwinger Multichannel method and the long-range part on the potential curve of the bound HCl⁻ anion. We have calculated cross sections for vibrational excitation and dissociative electron attachment. For all collision processes where quantitative experimental data are available, the new model agrees with experiments better than the previous model.
