摘要
用同步辐射角分辨紫外光电子能谱对ＣＯ与Ｃｓ在Ｒｕ（１０１０）面上共吸附的研究结果表明，由于Ｃｓ的强烈影响，ＣＯ的分子轨道重新排列．对应清洁表面上ＣＯ分子的（５σ＋１π）轨道的７５ｅＶ谱峰分裂成两个，分别处于６３和７８ｅＶ，６３ｅＶ谱峰关于一个垂直于Ｒｕ（１０１０）面而平行于〈０００１〉晶向的镜象面反对称性．
Abstract The molecular orbits of CO are rearranged
under the strong influence of coadsorbed Cs atoms.The peak for CO on clean Ru(1010) surface,at
7.5eV BE attributed to the 5σ and 1π orbits,is split into two peaks with one at 6.3eV BE and the
other at 7.8eV BE.The former peak shows an anti symmetry character about the plane parallel to
the 〈0001〉 crystallographic direction in the surface.
