| Abstract: | We discuss results of neutron time-of-flight spectroscopy on powder samples of C60, K3C60, and Rb3C60. Model calculations show that the excitation spectra can be well understood within the framework of lattice dynamics of a molecular crystal. Indications for a weak anomalous temperature dependence of low-energy phonons are observed for K3C60. |
