Correlation between the energy shell structure and geometry in metallic nanoclusters: Quasiresonance states, isotope effect

摘要

Metallic nanoclusters displaying electronic shell structure exhibit the special feature of a correlation between their geometry and the number of delocalized electrons. Their shape evolution can be described as a quantum oscillation between quasiresonant states (prolate and oblate configurations) whose amplitudes depend on the degree of shell filling. The picture explains the evolution of absorption spectra and predicts a peculiar isotope effect. (C) 2008 American Institute of Physics.
