· Phys. Rev. Lett.
We study the Fermi surface of Bi{sub 2}Sr{sub 2}CaCuO{sub 8} using angle resolved photoemission spectroscopy (ARPES) with a momentum resolution of {approx}0.01 of the Brillouin zone. We show that, contrary to recent suggestions, the ARPES derived Fermi surface is a large hole barrel centered at ({pi},{pi}), independent of the incident photon energy. We caution that the photon energy and k dependence of the matrix elements, if not properly accounted for, can lead to misinterpretation of ARPES intensities.
