It is shown that negative ions can be ejected from gas-phase water molecules when bombarded with positive ions at keV energies. Emission of both H- and heavier (O- and OH-) anions is observed. Electronic excitation and ionization processes are shown to play a decisive role in cation-induced anion formation.
