The ground state energy shifts and excitation spectra of charged buckminsterfullerene C_60^n-, n=1,... 5 are calculated. The electron--vibron Hamiltonian of Part I is extended to include all A_g and H_g modes with experimentally determined frequencies and theoretically estimated coupling constants. Complex splitting patterns of H_g vibrational levels are found. Our results are relevant to EPR measurements of spin splittings in C_60^2- and C_60^3- in solution.

... will be of interest for further testing of this theory. As found in Part I, degeneracies in the electron and vibron Hamiltonians give rise to a dynamical Jahn Teller effect, and to a considerable enhancement of the electronic pairing interaction. This helps to overcome repulsive Coulomb interactions and has important implications for superconductivity in K_3C_60 and the insulating state in K_4C_60.
