Polarized Cu L3-edge X-ray absorption spectra (XAS) of oriented film of Bi 2 Sr 2 Ca 1 Cu 2 O y have been measured to determine the symmetry of the orbital of the electronic holes. The states with the configuration 3d9L (L indicates ligand holes) have been detected. The holes d in superconducting materials are found to be in the antiferromagnetic band with b1 symmetry, derived by the Cu 3dx2 - y2 orbital, but also in a second band with a1 molecular symmetry, derived by Cu 3dz2 - r2 orbital at the Cu site. Our results can be rationalized with the formation of both d (b1) L and d (a1) L states in the ground state of this high-T c superconductor.
