abstract = {Using spin-resolved time-of-flight momentum microscopy, the
Rashba splitting of the Tamm surface state is investigated.
This state resides at the Fermi level in a projected bulk
band gap of the close-packed (0001) surface of hcp Re. The
Rashba splitting amounts to 0.4Å$^{−1}$. The state with
smaller parallel momentum is fully separated from bulk
states, whereas the Rashba branch with larger momentum
hybridizes with bulk states, which leads to a suppression of
spin-momentum locking. We find a good agreement of the
experimental results with one step photoemission
calculations that are based on ab initio theory within the
local density approximation. The spin polarization of the
inner Rashba state is not complete, which manifests in the
occurrence of quantum interference patterns as observed by
scanning tunneling microscopy. A one-to-one agreement of
scanning tunneling spectroscopy and photoemission results is
observed, suggesting that the quantum interference pattern
originates from the inner Rashba state.},
