KW - multi-atomic resonant photoemission, electronic correlation effect, Feynman diagram.
AB - <p style="text-align: justify;">A graphic method for studying multi-atom resonant photoemission process
in molecules and solids is presented in this work. The Feynman diagrams have been
applied to describe the interactions between atoms in MnO molecules. The theoretical
results show that the resonant contribution exhibits a strong distance-independent and
element specific effects for the neighboring atoms. Two mechanisms, the interactions
between the atoms and the reabsorption process have been supposed in the present
work to explain the multi-atomic resonant photoemission for the first time.</p>
