Abstract

We present the optical response of K₃C₆₀ and Rb₃C₆₀ single crystals in their normal and superconducting phase. Above T_c the optical conductivity is characterized by two components: a Drude one due to the free charge carriers and a mid-infrared absorption. Below T_c the data clearly indicates a superconducting gap in agreement with the weak coupling limit of the BCS theory, suggesting furthermore that high frequency intramolecular phonon modes are relevant for the pairing mechanism.
