SYMMETRIES OF JAHN-TELLER STATES IN CHARGED FULLERENES

摘要

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)~-.
