Oxygen Adsorption on UNi sub 2 Studied by HREELS, AES and XPS

HREELS, AES and XPS have been jointly used to study the adsorption of O sub 2 on the UNi sub 2 surface. It shows that oxygen interacts mainly with the uranium sites, leading to Ni precipitation through the surface underlayers. The HREELS results suggest the presence of two O--U sites having differen...

Description
Summary:HREELS, AES and XPS have been jointly used to study the adsorption of O sub 2 on the UNi sub 2 surface. It shows that oxygen interacts mainly with the uranium sites, leading to Ni precipitation through the surface underlayers. The HREELS results suggest the presence of two O--U sites having different adsorption kinetics. 6 ref.--AA
