palladium hydride indicate that there is no short-range ordering associated with the order-
disorder phase transition that occurs in the neighborhood of 50 K. However, measurements
of the line shape in the range 10–30 K show a change from a Gaussian to a non-Gaussian
profile. This effect is not related to the order-disorder phase transition. A possible
explanation in terms of thermally assisted tunneling is proposed.

Abstract
Measurements of the proton magnetic resonance absorption line shape in β-phase palladium hydride indicate that there is no short-range ordering associated with the order-disorder phase transition that occurs in the neighborhood of 50 K. However, measurements of the line shape in the range 10–30 K show a change from a Gaussian to a non-Gaussian profile. This effect is not related to the order-disorder phase transition. A possible explanation in terms of thermally assisted tunneling is proposed.
