Abstract

Electronic properties of germanium-fluorine cluster anions (Ge_nF^-_m; n = 1-11, m = 1-3) were studied using photoelectron spectroscopy (PES) with a magnetic-bottle type electron spectrometer. Compared between the PES of Ge_nF^- and those of the Ge^-_n, it was found that the doped F atom in Ge_nF^- deprives each Ge^-_n cluster of the excess electron without any serious rearrangement of the Ge_n framework. The F doping method enables us to estimate the HOMO-LUMO gap of the corresponding neutral Ge_n clusters (n = 4-11). For a diatomic GeF^- cluster, furthermore, the vibrational structures could be resolved to determine its vibrational frequency.
