用电子能量损失谱研究了C_（60）在Au（110）、K/Au（110）c（2×2）和K多层膜上的价带激发、C_（1 s）芯能级激发和振动模式，确定了C_（60）单层膜中的电荷转移.转移的电子分别为1±1、3±1和6±1。这些结果表明C60在这种金属表面上的强化学键合。
The charge transfer per molecule in a C60 monolayer on Au(110), on K/Au(110)c(2×2), and on a K multilayer has been determined by studying the electronic excitations from the valence bands and from the C 1s core level and the vibrational modes of the systems by electron energy loss spectroscopy. The electrons transferred are 1±1, 3±1, and 6±1, respectively. These results indicate strong chemical bonding of C60 on such metal surfaces.
