The oxidation reaction of Ti(0001) surface by oxygen molecules was observed by real-time in-situ photoemission spectroscopy using synchrotron radiation in the conditions of 400C and 3.710 Pa. The uptake curve of oxygen showed a plateau at the dose of 45-85 L and then increased again. This re-growth of oxide film was attributed to the drastic change of Ti oxidation state from TiO to TiO. Consequently, the characteristic change of the uptake curve was caused by the oxidation state change of Ti atoms.
