Angle-scanned photoelectron diffraction of the Cu
3p3/2 photoelectron peak of a Cu(111) surface measured with left- (C−) and right-handed (C+) circularly polarized light at = 679.5 eV and = 600 eV. Three pairs of azimuthal distribution curves are measured at polar angles of 35°, 55° and 70°, cutting across the [110], the [100] and an arbitrary crystal direction, respectively. The curves are symmetrized for a slight difference in the degree of polarization at the two beamline settings. Sparse markers are drawn at every tenth data point. |
