摘要：

Fluctuations of a rubidium atom on the surface of a fullerene cage have been observed by measuring the electric susceptibility of isolated RbC60 molecules. The evolution of the susceptibility with the temperature is perfectly reproduced with a very simple statistical model of relaxation. The con elation time for these fluctuations and the activation energy (E-a = 0.02 eV) for the motion of the alkali-metal atom on the C-60 surface have been determined.
