Abstract

Detailed analysis of the highest occupied molecular orbital band shape in the photoelectron spectrum of gaseous $C_{60}$ reveals a dynamic Jahn-Teller effect in the ground state of $C_{60}^{+}$ . The direct observation of three tunneling states asserts a $D_{3 d}$ geometry for the isolated cation, originating from a strong vibronic coupling. These results show that the ionic motion plays an important role in the electron-phonon interaction.
