| Abstract: | The static study has shown that the excited state with electron-hole pair in C60 can cause the distortion of the bond structure to form a polaron-like exciton with symmetry D5d. This paper further reveals the relaxation process from the initial electron-hole pair state to the polaron-like exciton by solving the dynamical equations. The relaxation time of this dynamical process can be determined from the time-dependent bond distortion with time step 4 femtoseconds. |
