Wehave studied by angle-resolved photoelectron spectroscopy (ARPES) the band structureof the ordered surface alloy obtained by the deposition of0.33 monolayers of Pb on the Ag(111) surface. We observeseveral dispersing features which are well described as Pb-Ag hybridbands by a band structure calculation performed within the generalizedgradient approximation of density functional theory. We also find thata band of mixed Pb p_z and Ag s characteris split in momentum space. We interpret this splitting asthe combined result of spin-orbit interaction and broken inversion symmetryat the surface.
