摘要：

A pseudo-Jahn-Teller model describing central atom distortions is proposed for endohedral fullerenes of the form A@C-60 where A is either a rare gas or a metal atom. A critical (dimensionless) coupling g(c) is found, below which the symmetric configuration is stable and above which inversion symmetry is broken. Vibronic parameters are given for selected endohedral fullerenes.
