Figure 6
2D momentum (kx, ky) distribution of the photoelectron intensity of the Au(111) surface at the Fermi level plotted on a logarithmic contrast scale. Measurements were performed with V-pol. at hν = 20 eV (a, c), H-pol. at hν = 20 eV from the BL7U branch (b) and p-pol. at hν = 100 eV from BL6U (d). (e) High-resolution measurement taken using p-pol. at hν = 80 eV from BL6U. In (c) and (e), the sample is in-plane rotated by ϕs = −30°. The upper left insets describe the experimental geometry of the electric vector of the incident light.
