| Outline of Final Research Achievements |
Element and atomic-site selective information on the electronic structure can be obtained from the photoelectron diffraction (PD). We have developed methods and analyzers for measuring orbital magnetic quantum numbers from PD circular dichroism. We discovered that circular dichroism also appears in the resonant Auger electron diffraction at the L-shell absorption edge. This effect (2-hole generation) is significant in 3d transition metals, especially in late transition metals from Cu to Fe. On the contrary, in the early transition metal compounds such as TiO2, the resonance photoelectron emission of 1-hole generation became dominant, and it was shown that the specific band dispersion was emphasized and observed elementally. Furthermore, we studied the resonance process at the K-shell absorption edge of light elements, and found a resonance Auger transition process in graphite, in which the total momentum of two electrons is conserved, which is different from ordinary photoelectrons.
