K-shell excitation ofD2O andH2O ice: Photoion and photoelectron yields

Abstract
The yield of photoelectrons and photoions from condensed H2O and D2O ice near and above the oxygen K edge is reported. Results of studies in the near-edge region indicate that Rydberg excitations, which are quenched in the bulk, survive, to some extent, on the surface. Analysis of the extended x-ray absorption fine structure of the photoelectron yield above the edge yields an oxygen-oxygen scattering phase shift in good agreement with theory.
