摘要：
Oxygen isotope exchange between a gas phase and a YBa2Cu3O7-delta crystal can pass through several stages. This effect is observed during isochronous annealings of a sample. It stems from the presence of sites and planes of different types in the crystal lattice. The site-planar effect observed here might be utilized to study the mechanism for the diffusion of oxygen atoms and also to synthesize crystals with given isotope compositions in the various sites of the oxygen sublattice.
