Electronic-structure-induced deformations of liquid metal clusters

Abstract
Ab initio molecular dynamics is used to study deformations of sodium clusters at temperatures K. Open-shell Na cluster has two shape isomers, prolate and oblate, in the liquid state. The deformation is stabilized by opening a gap at the Fermi level. The closed-shell Na remains magic also at the liquid state.
