Abstract
Crossed beam experiments have been performed to study elastic scattering and vibrational excitation in e-H2O collisions for the energy range from 1 to 10 eV. The rise of the cross sections at low energies (below 2 eV) is interpreted in terms of a direct scattering mechanism, whereas the broad enhancement of the cross sections around 6 to 9 eV is attributed to H2O-states intersecting the Franck-Condon region in this energy range. Theoretical estimates for the energies of H2O-states are not in agreement with these findings.Keywords
