F. Hagelberg et al., ELECTRIC-FIELD GRADIENTS FOR SMALL ANTIMONY BASED ZINTL CLUSTERS FROMHARTREE-FOCK INVESTIGATIONS, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 51(5-6), 1996, pp. 557-559
Electric Field Gradient (EFG) calculations have been carried out for A
ntimony based clusters with 20 and with 22 valence electrons. It is sh
own that EFGs are very sensitive to structural changes of the clusters
under study. This feature can be used to demonstrate the validity of
the Zintl-Klemm-Busmann principle for these systems through EFG determ
inations.
