摘　　要：通过对Ｃｅ－Ｃ（６０）多层膜电阻的原位观测，我们发现在Ｃｅ层上沉积Ｃ（６０）时，样品电阻有明显上升．这与以往研究过的其它金属（如Ｓｎ，Ａｇ，Ｃｕ等）－Ｃ（６０）体系的结果有很大差异．我们认为稀土元素Ｃｅ与Ｃ（６０）间可能有某种新类型的相互作用．Abstract By measuring the resistance in situ during the deposition of C60 on ultrathin rare-earth-metal Ce layers at UHV system, we find the resistance increases sharply. This differs completely from the results obtained on other kinds of metal (Cu, Cr, Sn etc.)-C60 interfacial system. It implies the existence of a new type of interaction between Ce and C60.
