Electronic properties of silicon and germanium atom doped indium clusters, InnSim and InnGem, were investigated by photoionization spectroscopy of the neutrals and photoelectron spectroscopy of the anions. Size dependence of ionization energy and electron affinity for InnSi1 and InnGe1 exhibit pronounced even-odd alternation at cluster sizes of n = 10-16, as compared to those for pure Inn clusters. This result shows that symmetry lowering with the doped atom of Si or Ge results in undegeneration of electronic states in the Id shell formed by monovalent In atoms.
