Goal: study the reaction of H2O ice overlayers with UThOx under light and in the dark. Implementation: Thin films of UThOx were prepared by codeposition from Th and U target on a Al foil substrate. The U/Th ratios are indicated in the labbook (approximate val...

Goal: study the reaction of H2O ice overlayers with UO2+x under light and in the dark. Implementation: Deposit thin films of UO2 on Si(111) substrates. Deposition is done by reactive sputtering of a U targets by an Ar plasma in presence of oxygen (O2). Films ...

The surface reduction of films of the mixed oxide of uranium U−Pu−O2 with adsorbed water ice was studied by ultraviolet and X-ray photoelectron spectroscopy (UPS and XPS, respectively). The films were produced as thin films by reactive sputter deposition. Wate...
