Abstract
Electron impact ionization and dissociative ionization of water in vapour and ice form has been studied using a newly developed apparatus comprising a well-collimated beam of 700 eV electrons, a cryogenic target assembly and a quadrupole mass spectrometer. The target assembly consists of a liquid-nitrogen cooled nickel foil upon which a thin layer of ice is formed. Comparison of the vapour-phase mass spectrum with that obtained in the ice phase reveals significant differences in the dissociative ionization pattern which are of significance in modelling studies of cold astrophysical environments.
