| We show that band electrons in AnC60 crystal (C60 fullerene doped with alkali ions A) are in highly chaotic quantum state. We describe intensity of the chaos by means of the Shannon information entropy, which we calculate using single particle Bloch functions. The entropy provides a quantitative measure of scars as well as degree of electrons delocalization in gaps between C60 molecules. Implications of our results for conductivity in A3C60 are discussed. |
