Polarization and Structure of Small Clusters
W. Geertsma
In this paper we report the structure of the Li4Ge4 cluster as a function of charge transfer and polarizability. We find that for small charge transfer (Q < 0.5) this cluster has t…

Polarization and Covalency in Alkali-Tetralide Clusters
Wiebe Geertsma
In this paper we discuss the structure of A4M4 alkali(=A)- tetralide (= M) (= group 14) clusters. Without polarization these polyions consist of a central tetralide tetrahedron wit…
