A new approach to analyse H⊗(2h⊕g) Jahn-Teller system for C60

It is now well-know that electron (hole)-vibron coupling and hence Jahn-Teller (JT) effect is important understanding the properties of C-60 and related molecules. In this paper, we study H circle times (2h circle plus g) coupling case to find the potential energy surfaces for the positively charged C-60 molecule due to distortion. The H circle times (2h circle plus g) Jahn-Teller system is of particular importance as this will be the JT effect displayed by C-60 molecules removed with an electron. C-60(+) is obtained by removing one electron from fivefold degenerate Hu highest occupied molecular orbital (HOMO) and a hole in HOMO interacts with the vibrational modes of C-60 and symmetry is broken. We apply the method of symmetry breaking mechanism to obtain expressions for the potential energy surface.
