| Abstract: | By using laser ablation on mixtures of coinage metals M (Cu, Ag, Au) and lead, M/Pb binary cluster anions containing up to tens of atoms were produced and analyzed. Most of the magic clusters discovered can be described based on the electron shell models which were deduced from simple homogeneous metal cluster systems. The clustering activities of coinage metals and lead were also compared with the properties of their bulk binary alloys. |
