N2 - The microstructure of nanocrystalline Pd was investigated by small-angle neutron scattering. The strong scattering signal is interpreted as originating from crystallites embedded in a matrix formed by incoherent interfaces. From the scattering curves size distributions were determined, which yield an average radius of 2-6 nm. The volume fraction of the crystallites was found to be about 0-3, and the atomic density in the matrix about one-half that of Pd crystals. Structural parameters varied from sample to sample. An appreciable volume fraction of voids or interconnected channels may exist in some of the specimens.
