Self-expansion patterns of unconstrained assemblies of charged particulates are considered. As the assemblies cannot be described, in general, in the context of a continuum comprising massless charged entities, the complete equation of motion is applied for each member of the assembly. It is shown that irrespective of the initial positions of the particulates, when expanding in free space or else they are identical in size and mass, the assembly tends toward a spherical shape, with characteristic inner structure. Examples of simulations are presented to this end.

    Ab initio calculations that explicitly include spin-orbit interactions are reported for the NeCl2 system of electronic states. A surprising curve crossing is observed for the C2v, T-shaped geometry. Away from the C2v geometry, the states mix, as expected. On the basis of these new results we...
