Abstract

The Debye—Waller parameters were determined at room temperature and around 90 K for palladium metal powders with different particle sizes. The effective values obtained were divided into the dynamic component Bd, which is due to the thermal vibration of the constituent atoms and are temperature dependent, and the static component Bs, which is probably due to the static displacement of the atoms and is temperature independent. The Debye temperature θD calculated from the component Bd decreased with the increase in the component Bs, of which the relation was able to extrapolate to the θd-value determined on single crystals at Bs = 0. The decrease in θD was qualitatively explained by using a simple core-shell model, the shell part having as low a θD-value as 140 K.
