Abstract
Nuclear acoustic resonance (NAR) has been observed in tantalum single crystals with low concentrations of hydrogen (7.8 and 16 ppm) between 4.2 K and room temperature. The temperature dependence of the Δm=1 transition is reported for the first time. For the Δm=2 transition the temperature dependence of the linewidth is analysed in terms of the precipitation of a hydride phase in the Ta-H system. The differences in linewidth between virgin and pre-cooled runs can be interpreted by the effect of dislocations generated during the precipitation.
