摘要：

Defect cascades produced by fast neutron irradiation of YBa2Cu3O7-delta single crystals were studied by transmission electron microscopy. The visible defects were found to have sizes between 1 and 5 nm. Defect densities were obtained as a function of neutron fluence between 2 x 10(21) and 8 x 10(21) m-2 (E > 0.1 MeV) and compared to damage calculations. The measured defect density scales linearly with fluence and amounts to 1 x 10(22) m-3 at a neutron fluence of 2 x 10(21) m-2. The defect stability was studied at room temperature and through annealing to 400-degrees-C.
