Abstract
We present angle-resolved photoelectron measurements of YBa2Cu3O7-delt a single crystals cleaved perpendicular to the c axis. The results rev eal photon energy dependent features in the dispersion of the sharp 1 eV peak, surface induced modifications in the electronic structure and a high surface sensitivity to adsorption of atomic hydrogen.
