SE yield and opaque fraction for a polar angle of 35° with respect to the (111) plane. The azimuthal angle around the [111] direction is measured with respect to the direction. (a) Experimentally obtained dependence of the SE yield on the azimuthal angle. He⁺ PEs are 15 keV (red, solid line) and 33.6 keV (blue, dashed line). The insets present the view of the crystal along the two indicated directions. The color code is as follows: gold: 1st layer, silver: 2nd layer, and red: 3rd layer. (b) Calculated opacity of a gold crystal lattice (14 atomic layers). The used effective atomic diameter is 0.68 Å.
