AB  - Inelastic electron tunneling spectroscopy of Ce-2@C-80 dimetallofullerenes reveals a low-energy inelastic excitation that is interpreted using ab initio calculations and associated with the movements of encapsulated Ce atoms inside the C-80 cage. The electron-vibration interaction in Ce-2@C-80 is unusually high, inducing a pronounced zero-bias anomaly in differential conductance of Ce-2@C-80. Our observations show that the atoms encapsulated in fullerene cages can actively participate in determining the properties of molecular junctions.
