| Outline of Final Research Achievements |
We developed a two-dimensional display-type angle-resolved photoelectron analyzer with a high energy resolution. It is expected to be applied to a method called photoelectron holography that visualizes local atomic arrangements. Conventionally, it was difficult to distinguish chemically different sites with the same central element. With the high energy resolution achieved in this work, such experiments become possible. In photoelectron holography, it is also required to measure photoelectron angular distributions over a wide angle range. The developed analyzer is advantageous because it has a very wide photoelectron acceptance angle. We also experimentally verified the method to increase the energy resolution, and confirmed its effectiveness.
