Abstract

We study the Fermi surface of

{Bi}_{2} {Sr}_{2} {CaCu}_{2} O_{8}

using angle resolved photoemission spectroscopy (ARPES) with a momentum resolution of

\sim 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

(π, π)

, 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.
