Abstract
The crossed-beam technique has been used to measure differential cross sections for vibrational excitation in e-HCl collisions from threshold (Eth=0.357 eV for v=1) up to 8 eV. The excitation function for the v=1 level shows a sharp peak close to threshold, a second maximum of larger width around 2.5-3 eV and a monotonic decrease above 3 eV. The angular distribution measurements give nearly isotropic scattering for this process indicating the dominant role of a resonance mechanism via the HCl-2Sigma+state in this energy range. The absolute cross section in the threshold peak, integrated over all angles, is estimated to 1.3 * 10-15cm2+or- 50%.Keywords
