| 英文摘要 | The electron-phonon interaction in C-70 anions is studied by making use of a lattice We find there exists a Jahn-Teller effect in C-70(3-) system, due to an extra electron being doped to the double degenerate E-1 '' state. As a result of this effect, the original D-5h symmetry of the ground state becomes unstable, which causes distortion of the lattice configuration. The only symmetry maintained in the final state of the relaxation is the x-y plane reflection symmetry. We further find that besides the Jahn-Teller active A(1)', A(2)' E-2' modes, the non-Jahn-Teller active E-1' vibrations also contribute to the relaxation process. The E-1' components come from the nonlinear effect and are two or three orders smaller than those of the Jahn-Teller active modes. We suggest that the C-70(3-) molecule is a promising Berry Phase candidate in this effective E x e Jahn-Teller system. |
