文摘The electronic structure of Ag_n and Au_n(n=2,3,4) calculated by DV—X_α method, are different each other, and the ionization potentials of Ag_n and Au_n as a function of cluster size n exhibit an interesting 'saw—tooth' behavior. The interactions between atom Ag—Ag and Au —Au in Ag_2, Au_2 for different bond length are analyzed. The DOS of the orbitals shows those interactions directly.
