Abstract
We study the Fermi surface of Bi2Sr2CaCu2O8 using angle resolved photoemiss ion spectroscopy (ARPES) with a momentum resolution of similar to 0.01 of t he Brillouin zone. We show that, contrary to recent suggestions, the ARPES derived Fermi surface is a large hole barrel centered at (pi, pi), independ ent 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.
