Excitonic polaron in the photoemission spectra of C-60 and the origin of high-Tc superconductivity of doped fullerenes
Alexandrov A.S., Kabanov V.V.
The photoemission spectrum of in a wide energy region is well described with the small polaron theory and the polaron-exciton coupling. The strongest coupling is found with the pinch Ag2 mode and with ~ 0.5 eV Frenkel exciton.
