Vibrational properties of polymer and quenched CsC

We report new results on the vibrational dynamics of polymer and quenched CSC60 phases. Both the splitting and the structure of new activated lines of polymer CsC60 are in agreement with the lowering of C60 molecular symmetry from Ih to D2h. An inelastic neutron investigation on polymer and quenched CsC60 is reported. It allows one to identify the vibrational signature of the low-temperature (T < 150 K) ordered monomer phase on quenched CsC60
