A deformed jellium model is used to calculate the fission barrier height of [Formula: see text] within the Kohn-Sham density-functional theory (i.e., including shell effects). Although the shape of the barrier obviously depends on the parametrization of the fission path, we have found that the saddle point corresponds to a configuration in which the emerging fragments are already formed and rather well apart. From this result, we offer a simple way to calculate the barrier height for charged trimer emission from alkali-metal clusters of (almost) arbitrarily large size and charge state.

Electronic shell and supershell structures in trivalent-metal clusters exhibit large discrepancies with the results of the conventional jellium model. For gallium the beat location in the supershell pattern is found around Ne=2500 valence electrons, in disagreement with the jellium model prediction Ne=1150. The discrepancies can be explained by a slight softness increase of the effective electronic potential at the surface. Theoretical calculations, taking into account ion pseudopotentials, within both local and nonlocal approaches, show that this softness arises to a large extent from the non-Coulombic short-range electron-ion interaction.
