Abstract:

Optical absorption spectra of radical anion C60- after light alkali-dopping have been studied by using an extended Hubbard model and two distinct induced spectra have been obtained. The result is in agreement with the experimental one. The spectra have been assinged theoretically and the reason for the induced spectra generation has been discussed.

Key words: C-60, Extended Hubbard model, Optical absorption
