Abstract
Bimetallic Ag-Pd clusters have been synthesized by radiation-induced r eduction of aqueous solutions of metal sulfate salts with different Ag -I/Pd-II ratios in the presence of polyacrylic acid. The mixed cluster s have been characterized by TEM and UV-visible spectra. The evolution of the optical absorption spectrum with the dose absorbed and the ele ctron diffractograms support the conclusion of the formation of an int imately alloyed cluster of AgxPd1-x. The maximum wavelengths of the ex perimental absorption spectra at variable x coincide with those calcul ated from the electron density in an alloyed cluster.
