However, the crystal has a disorder in the occupation of the Cs atom and it should be taken into account because the disorder of the alkali atom is considered to affect significantly to the superconductivity (Ref. 6). On the other hand, there is no disorder in (Formula presented) at low temperature and this enables us to extract the effect of the local symmetry on the superconductivity in alkali fullerides.
