Introduction
 
Over the last few years a many-body 1/N dynamical model has been developed to explain charge transfer between between simple atoms and metal surfaces [1-3] . By simple atoms we mean atoms with simple s-orbitals, e.g. alkali and alkaline earth atoms. In our work we extend this model to more atoms with more complex electronic structure, e.g. oxygen atoms with p-orbitals where the spin-orbit coupling begins to play a part in the charge transfer. 

Currently we have worked out the case for resonant charge transfer between oxygen and metal surfaces.
