Abstract
The electronic excitation process by low energy electron impact is studied theoretically for the case of O2 molecules physisorbed on a model jellium metal (Al). The spin forbidden excitations to the a 1Δg and b 1Σ+g states are considered. Only the resonant contribution corresponding to the 2Πg O−2 resonance, which dominates at low energy in the free molecule is included in the present work. The characteristics of this resonant process involving a resonant state hidden below the excitation threshold are analyzed; in contrast with the free molecule case, a very important excitation process occurs below the energy threshold. The dependence of the excitation process on the symmetries of the problem is also discussed.
