Multiphoton photodetachment of C60- -: art. no. 064302

A model delta-function potential is considered for simulating the interaction of the attached electron in C-60(-) with the fullerene environment. The analytical expressions for the energy eigenstates, and the Green's function, are used to deduce the one-, two-, and three-photon photodetachment probabilities for C-60(-). Particularly interesting is the observation that the three-photon photodetachment is greatly enhanced by the bound states with energies close to the energies for resonant absorption of one and two photons, and a resonance in the l=3 state.
