✦ Synopsis

It is a general observation that local maxima in charge distributions of many-electron systems occur only at the positions of nuclei. Gatti, Fantucci and Pacchioni have recently shown that non-nuclear maxima are found in the charge distributions of Li clusters. This paper reports on the same behaviour for Na clusters. The discovery of non-nuclear maxima in clusters of both Li and Na atoms, together with the observation that the properties of the resulting pseudo atoms as determined by the theory of atoms in molecules are similar for both sets of clusters, suggests that non-nuclear attractors may be typical of the alkali metals and are responsible for their characteristic properties.
