Resumen:
TDPAC measurements were carried out on111In-implanted α-Nb2O5 samples at room temperature, after isochronal annealings up to 1270 K in 200 mbar oxygen and up to 1070 K in 10−5 mbar, respectively. The observed hyperfine interactions were compared to point charge model calculations which predict 15 and 2 equivalent cation sites in α-Nb2O5 and NbO2. The data in each system could be reproduced with one antishielding factor β=Vzz exp/VzZpc for all sites, i. e. β(Nb2O5)=19.2 and β(NbO2)=31.2, respectively.
