Abstract
The connection between local structure and the grain size distribution in nanophase palladium is studied by XAFS and x-ray diffraction (XRD) . We show that there is a reduced average coordination number in all s amples; this reduction is compatible with a size effect, contradicting previous XAFS measurements. Both a first shell analysis and a full an alysis up to the 8th coordination shell, including multiple-scattering are reported.
