Symmetries of Jahn-Teller States in Charged Fullerenes
The dynamical Jahn-Teller effect of positively charged fullerene C 60 + is studied systematically within the Bogoliubov-de Gennes formalism, in the presence of Coulomb interactions with full respect of the icosahedral symmetry. With a hole in the electronic HOMO state, the study on the static Jahn-Teller effect shows that D 5d is the most stable configuration for C 60 + . The dynamical Jahn-Teller effect of C 60 + due to the quantum tunneling between the six equivalent D 5d states is also studied which shows a higher potential barrier between the equivalent minima than that of C 60 - .
