N2 - The speed of D-H replacement in D-implanted BaCe1-XYXO3-δ and SrCe1-XYbXO3-δ, exposed to H2O vapor at room temperature has been studied as a function of X by use of the ERD technique with MeV He+ ion beam. The decay curve of D and growth curve of H in the specimens have been measured as a function of exposure time, and the decay constants of D, namely the D-H replacement speeds, have been obtained from the experimental curves. It is found for both specimens that the decay constants of D, proportional to the absorption coefficient and the molecular formation coefficient of HD, increases and then after a maximum at X = 0.05-0.10 decreases as X increases and the absolute experimental values for BaCe1-XYXO3-δ are larger by an order of magnitude than those of SrCe1-XYbXO3-δ.
