Phys. Rev. B 65, 033407 (2001) [4 pages]Spin-orbit splitting of the L-gap surface state on Au(111) and Ag(111)Received 27 August 2001; published 28 December 2001 We present high-resolution photoemission results on the L-gap surface state on Au(111) and Ag(111), in combination with fully relativistic density-functional calculations. In the case of Au(111), both experimental and theoretical results demonstrate that the lack of inversion symmetry at the surface leads to a considerable spin-orbit splitting of this surface state over the whole Fermi surface, whereas in the case of Ag(111) this splitting is far too small to be experimentally resolved in our data. © 2001 The American Physical Society URL:
