摘要：

We show that Berry's phase exists in the Jahn-Teller-distorted anionic and cationic fullerenes, C60 +/-. Berry's phase helps recover the ''missing'' zero-point vibration energy by generating a finite pseudorotational angular momentum, enhances the Jahn-Teller distortion, and restores the ground-state degeneracy back to the value before distortion.
