The yield of photoelectrons and photoions from condensed H20 and DqG ice near and above the oxygen E 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 oxygenoxygen scattering phase shift in good agreement with theory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
