Abstract

Abstract: The electronic affinity energies, E_A values, geometric and electronic structures of CoGe^-_n(n=1~12) clusters are studied experimentally and theoretically. The E_A values measured by a photoelectron spectroscopy agree with the computational ones for CoGe^-₈, CoGe^-₉and CoGe^-₁₀. From the PDOS, the interactions of p, d and s electrons were analyzed. The stability of CoGe^-_n was discussed and CoGe^-₁₀ was considered as a cluster with magic number.

Key words: CoGe^-_n cluster, Density functional theory, Electronic affinity energy, E_A values, PDOS
