摘要: Using a combination of two methods, pseudopotential scheme and density‐functional approximation for the correlation energy, equilibrium geometries clusters Nan up to n=8 have been studied. The structures small sodium do not show any resemblance metallic lattice. Experimental ionization energies can be reproduced with maximum error 3%; alternancy in their dependence on n is described appropriately explained by means composed Na2 units.
