The electronic structures of germanium cluster (Gen; n=4-32) were studied by using photoelectron spectroscopy (PES) for Gen-, GenF-, and GenCl-. The halogen atom doping method enables us to determine the HOMO-LUMO gap of the corresponding neutral Gen cluster to be 0.8-1.0 eV around n=30. This result implies that the Gen cluster itself never emits visible emissions.
