Abstract
We propose a new class of Graphite Intercalation Compounds (GICs) cont aining C60 and alkali metals. The compound C32K4C60 is predicted and a ttempts to synthesize it using a C8K precursor and benzene-dissolved C 60 are reported. C8K samples exposed to C60 and benzene display a repr oducible resistive transition at 19.5K indicative of superconductivity . C8K samples exposed to benzene alone show no transition for T > 4.2K . Possible origins of the superconductivity are discussed.
