We study the Fermi surface of Bi{sub 2}Sr {sub 2}CaCu{sub 2}O{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. (c) 2000 The American Physical Society.
