测量了C60 单晶 (111)解理面法向发射的角分辨光电子谱 .利用同步辐射光源研究了对应于分子轨道HOMO及HOMO 1的能带的色散关系 .实验观察到HOMO和HOMO 1能带在Γ—L方向存在明显的色散 ,最大色散分别为 0 2 7eV和 0 42eV .色散曲线与理论电子结构基本符合
The angle-resolved photoelectron spectroscopy (EIS) of the (111) cleavage plane normal direction emission was measured.The synchrotron radiation source was used to study the dispersion relationship of the energy bands corresponding to HOMO and HOMO 1. The HOMO and HOMO 1 energy bands In the Γ-L direction obvious dispersion, the maximum dispersion were 0 2 7eV and 0 42eV. The dispersion curve and the theoretical electronic structure basically in line with
