摘要：

Oxidation of thin Li films to Li2O is found to be associated with the emission of exoelectrons and even ejection of O- ions. Cluster calculations demonstrate that electron transfer from the substrate causes formation of O-2(2-) Species which readily dissociate without noticeable activation barrier. The O- particles formed near the surface deexcite into 02- ions, partly non-adiabatically causing exoelectron emission, and a very small fraction may escape into the vacuum.
