QUANTUM-LATTICE FLUCTUATIONS AND LUMINESCENCE IN C60

We consider luminescence in photoexcited neutral C60 using the Su-Schrieffer-Heeger model applied to a single C60 molecule. To calculate the luminescence we use a collective-coordinate method where our collective coordinate resembles the displacement of the carbon atoms of the Hg(8) phonon mode and extrapolates between the ground-state ''dimerization'' and the exciton polaron. There is good agreement for the existing luminescence peak spacing and fair agreement for the relative intensity. We predict the existence of further peaks not yet resolved in experiment.
