Two-step Liquid Drop Model for Binary, Metal-rich Clusters

Abstract

It is shown that differences observed between the ionization potentials of the molecular-doped metallic clusters and those corresponding to the bare metallic ones can be explained by a two-step approach of the classical Liquid Drop Model. This approach takes into account the distinct physical properties of the interface between the molecular core and the metallic shell. Also, it is shown that the presence of the molecular core may act in the determination of the predominant channel of the coulombic fission.
