✦ Synopsis

Past investigations have correlated XPS valence band broadening with the increase in size of clusters of supported atoms on inert substrates. The theoretical effects of geometrical variation for a given cluster size has not been reported. In this report we show that the broadening effect can be due to size, but can also occur due to the geometrical variation within a given cluster. If a valence band density of states curve for the geometrical variations of the smallest possible cluster of MnO, namely (MnO),, is constructed, it is bulk like in appearance.
