The photoemission spectrum and the specific heat are studied in the Hubbardmodel of small clusters including orbital degeneracy. We focus on thedegeneracy and valence dependence in the limit of a large Coulomb interaction.For integer valence, it is found that the degeneracy increases the width of thephotoemission spectrum and it reduces the contribution from the charge degreesof freedom to the specific heat. A deviation from integer valence reduces thewidth of the photoemission spectrum.
