Angular resolved photoemission spectroscopy is used to map the Femi surface of Sb(111). In the region close to the T-point, we find multiple Fermi surface features. Utilizing the tuneability of Synchrotron radiation shows that these structures are not multiply connected, but can be associated with the bulk hole-Fermi surface and electron pockets originating from two 2D-bands crossing the Fermi level at K-F similar to0.1 and similar to0.05 Angstrom(-1). The energy dispersion of the latter band follows that of a rotational paraboloid with a circular Fermi surface. The cross section of the bulk hole-pocket in the mirror plane is compared with theoretical predictions. (C) 2004 Elsevier B.V. All rights reserved.
