Abstract
The surface structure of triuranium octaoxide (U3O8) and the effect of CO on surface behaviour have been studied by X-ray photoelectron spec troscopy (XPS). An intensity analysis of the composite U4f photoelectr on spectrum of U3O8 shows that this compound should be written at (U2U O8)-U-VI-O-IV. After exposure to 7.2 . 10(6) L CO (1 L = 1.33 . 10(-4) Pa . s), the oxygen content in the surface is decreased and the O1s/U 4f ratio decreases about 10%. The investigation indicated that the sur face layer of triuranium octaxide was partially reduced in the atmosph ere of carbon monoxide.
