We report calculated cross-sections and photoelectron angular distributions for photoionization out of the two outermost orbitals of GcH(4) for photon energies ranging from near threshold to 50 eV. The iterative Schwinger variational method in the exact static-exchange level is used to obtain the continuum photoelectron orbitals. Our calculated results show a remarkable similarity between the photoionization properties of the outermost valence orbitals of silane and germane. (C) 2004 Elsevier B.V.
