The O-D relaxation peak in niobium was studied over a wide temperature range, using elastic after-effect and internal friction at about 1 Hz and 1 kHz. Arrhenius temperature dependence of th relaxation times of the peak was found to exhibit a large nonclassical deviation below 100 K in a similar way as that of the O-H peak. Isotopic dependence was also shown to be nonclassical.
