Abstract

Photoelectron spectroscopy has been used to study the electronic structure of the newly discovered Bi-Ca-Sr-Cu-O superconductors. A clear Fermi edge is observed showing a metallic behavior. The oxygen

1 s

core level shows only one peak, in contrast to previous results on

Y {Ba}_{2} {Cu}_{3} O_{7 - δ}

. We suggest that the Fermi edge observed is mainly due to electrons derived from Bi-O

p

bands.
