The electronic structure of the high T/sub c/ superconductor Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7/ is probed with resonant photoemission and near edge x-ray absorption spectroscopy. The parameter, U, which is a measure of the Coulomb interaction between two 3d holes at the same site, is found to be 4.6 eV. The oxidation states of the Cu atoms are determined to be 2+, while 2p holes are observed on the oxygen atoms.
