摘要

从定域分子轨道描述的电子12态的空间和能量分布的信息对于理解分子14材料的电子和光学性质是重要的13。在本研究中，用安装在UVSOR-III同步加速器软17 X射线束线BL6U上的pho-16电子动量显微镜（PMM）测量了Au（111）上高度ori-15ente coronene单层的光发射光谱。以新安装的PMM appa-21装置为例，演示了该系统在宽动量空间上的全va-18能带映射和位置选择共振光电发射光谱。22

Resonant Photoemission Spectroscopy of Highly-Oriented-Coronene Monolayer using Photoelectron Momentum Microscope

Information of spatial and energy distribution of the electronic 12 state described from the localized molecular orbitals is important 13 to understand the electronic and optical properties of molecular 14 materials. In this study, photoemission spectra of a highly-ori- 15 ented-coronene monolayer on Au(111) were measured by a pho- 16 toelectron momentum microscope (PMM) installed at the soft 17 X-ray beamline BL6U of UVSOR-III synchrotron. Whole va- 18 lence band mapping across wide momentum space and site-selec- 19 tive resonant photoemission spectroscopy of this system were 20 demonstrated as a case study of the newly installed PMM appa- 21 ratus. 22
