      abstract     = {The valence band electronic structure of a BaTiO3-derived
                      oxide quasicrystal (OQC) is studied by photoemission using
                      momentum microscopy. An upward-dispersive O2p band is
                      identified, and it can be assigned to a combination of
                      in-plane orbitals according to the symmetry and the overlap
                      of the wave functions. In addition, the signature of Ti3d
                      states near the Fermi level is observed, which results in a
                      metallic character of the OQC with 3d1 occupation. Our
                      experiments reveal two-dimensional electronic states within
                      the OQC based on a symmetry-adapted decomposition of
                      photoelectron intensity distribution in the momentum space.},
