By means of low temperature STM and STS, excitations of Fe and Co atoms and clusters on a Pt(111) surface were studied. From combined photoelectron spectroscopies in the hard and soft X-rays as well as below 10 eV,differences between bulk and surface electronic structures were clarified.In LiV2O4, the recoil effects were observed in the valence band spectra. Meanwhile, the bulk/surface sensitivity of ELEPES was semiquantitatively discussed. Finaly, high efficiency spin-polarized photoelectron study by use of a Fe-O spin detector and a complete two dimensional kx-ky band mapping by a momentum microscope were discussed.

通过低温STM和STS，研究了Pt(111)表面Fe和Co原子和团簇的激发。通过硬X射线和软X射线以及10 eV以下的组合光电子能谱，阐明了体电子结构和表面电子结构之间的差异。在LiV2O4中，在价带谱中观察到反冲效应。同时，半定量地讨论了ELEPES的体/表面敏感性。最后，讨论了使用 Fe-O 自旋探测器进行的高效自旋偏振光电子研究以及动量显微镜的完整二维 kx-ky 能带映射。
