Electronic properties of germanium-fluorine cluster anions (GenF-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 GenF- and those of the Ge-n, it was found that the doped F atom in GenF- deprives each Ge-n cluster of the excess electron without any serious rearrangement of the Gen framework. The F doping method enables us to estimate the HOMO-LUMO gap of the corresponding neutral Gen clusters (n = 4-11). For a diatomic GeF- cluster, furthermore, the vibrational structures could be resolved to determine its vibrational frequency.
