 Abstract: We used angle-resolved photoemission spectroscopy to study the shadow
Fermi surface in one layer Bi2Sr1.6La0.4CuO6+delta and two layer
(Bi,Pb)(2)Sr2CaCu2O8+delta. We find the shadow band to have the same
peak width and dispersion as the main band. In addition, the shadow
band/main band intensity ratio is found to be binding-energy
independent. Consequently, it is concluded that the shadow bands in
Bi-based HTSC do not originate from atiferromagnetic interactions, but
have a structural origin.
