D2O adsorption and desorption behavior on Fe2O3 have been studied with a Fourier transform infrared absorption spectrometer (FT-IR). The absorption peaks of the O-D stretching vibration band were observed in the region of 2500-2750 cm-1, which were considered to be from the surface OD on the sample. Desorption behavior by irradiation of energetic particles was not uniform but depended on FTIR wave numbers. Hence, desorption of D2O was found to be heterogeneous on the surface.
