Fragment emission following multiple ionization in 20-200-eV e- + H2O collisions

Résumé

Collisions between 16-200 eV electrons and H2O target have been investigated experimentally. The fragment ions originating from single, double, and triple ionization were energetically analyzed at an observation angle of 90° with respect to the incident beam direction. Fragments with energies as low as 0.1eV were detected. From the spectra, cross sections for double and triple ionization, relative to single ionization cross sections, are derived. The present results are compared with previous experimental results involving several molecular targets, and with formulas that have been developed previously for electron-atom collisions.
