      abstract     = {We report high-resolution spin-resolved photoemission
                      spectroscopy (spin-ARPES) measurements on the parent
                      compound Sb of the recently discovered three-dimensional
                      topological insulator Bi1-xSbx (Hsieh et al 2008 Nature 452
                      970, Hsieh et al 2009 Science 323 919). By modulating the
                      incident photon energy, we are able to map both the bulk and
                      the (111) surface band structure, from which we directly
                      demonstrate that the surface bands are spin polarized by the
                      spin-orbit interaction and connect the bulk valence and
                      conduction bands in a topologically non-trivial way. A
                      unique asymmetric Dirac surface state gives rise to a
                      k-splitting of its spin-polarized electronic channels. These
                      results complement our previously published works on this
                      class of materials and re-confirm our discovery of
                      topological insulator states in the Bi1-xSbx series.},
