Abstract
Experimental energy bands mapped from normal-emission photoelectron spectra of and surfaces show four photoemission features that disperse in both materials in good agreement with band calculations. Segments of the Fermi surfaces mapped by angle-resolved photoemission spectroscopy in the plane of the Brillouin zones for both and are in good agreement with band calculations. This Fermi surface segment changes when one electron is added to , corresponding to , based on the rigid-band approximation.
