Figure 4
(a) CCD camera image of the manipulator (top) demonstrating the 45° rotation for the azimuthal axis (middle) and further polar rotation of ∼55°(bottom). (b) Linear polarization dependence of the Yb3+ 3d5/2 core-level spectra for cubic YbB12 by selecting the photoelectron-detection directions [100] (left), [110] (middle) and [111] (right). Insets are close-ups of the 1525.5 eV peak in the Yb3+ 3d5/2 spectra. The so-called Shirly-type background is subtracted as discussed in the literature (Kanai et al., 2015). |
