摘要

Electron propagator calculations in two approximations--the third-order algebraic, diagrammatic construction and the outer valence Green’s function (OVGF)--have been performed on the vertical electron affinities of C_(60) and the vertical electron detachment energies of several states of C_(60)~? with a variety of basis sets. These calculations predict bound ~2T_(1u) and ~2T_(1g) anions, but fail to produce ~2T_(2u) or ~2H_g anionic states that are more stable than ground-state C_(60). The electron affinity for the ~2A_g state is close to zero, but no definitive result on its sign has been obtained. This state may be a resonance or marginally bound anion. The OVGF prediction for the vertical electron detachment energy of ~2T_(1u) C_(60)~?, 2.63 eV, is in excellent agreement with recent anion photoelectron spectra.
