The room temperature Raman spectrum of EuC6 has been recorded and is found to exhibit a Fano-broadened band at 1500 ± 5 cm-1 and an additional feature at 1840 ± 10 cm-1. The latter feature is attributed to crystallites of EuC2. The Raman spectrum of EuC6 will be compared with the spectra of LiC6 and MC8, where M = K, Rb and Cs. A model incorporating the static structure factor for phonon scattering and the momentum selection rules in the Raman process will be presented and shown to account for both disorder induced scattering and zone folding effects. We suggest that these effects are merely the extreme cases of a continuous range of phenomena which depend in detail on the degree of order in a given GIC sample.
