Abstract
The appearance thresholds and kinetic energy spectra of fragment proto ns and deuterons produced in the dissociative photoionization of H2O a nd D2O by 20-40 eV photons have been measured. Measurements were made both along and at right angles to the E vector of the synchrotron radi ation to isolate states of different symmetry. The results show the im portant role of superexcited states in the ionization process and pred issociation and autoionization pathways have been identified.
