Elastic parameters (the Young's, shear, and bulk moduli; the Lamé parameter; the Poisson ratio; and the Debye temperature) and shear damping anomalies accompanied by the generation of excess heat (not less than 6 W) were observed between 116 and 190 K in deuterated palladium, PdD_0.719, suggesting dynamic interactions among deuterons squeezed between tetrahedral and octahedral interstices in the palladium face-centered-cubic lattice.
