X‐ray photoelectron spectroscopy has been used to study the surface of uranium metal cleaned by nitric acid treatment and argon ion etching, followed by heating in a high vacuum. The surface is shown to contain UO 2− x species over the entire temperature range studied. Heating to temperatures in the range 400–600°C generates a mixture of this oxide, the metal and a carbide and/or oxycarbide species.
