摘要：

PAC experiments in YBa2Cu3O7 - x were performed with 111 Cd populated from different parent nuclei, i.e. 111In, 111Ag and 111mCd. 111In can substitute at the Cu(1)-, the Ba- or the Y-site, depending on the annealing temperature. On the other side, 111Ag substitutes at the Cu(2)-site, whereas the measurements at 111mCd did not allow any site assignement. Channeling experiments performed with electrons and positrons emitted from 112mIn and 111mCd support this interpretation. © 1990.
