Plasmons in fissioning metal clusters

  • Published:
Zeitschrift für Physik D Atoms, Molecules and Clusters

Abstract

We study the plasmon response of Na18 ++ along its two most favorable (symmetric and asymmetric) fission paths. Strong symmetry breaking and unusually large difference between the ion and electron distribution give rise to strong Landau fragmentation of the resonance spectra which has not been observed in normal configurations near the cluster ground state. This carries forth in the multiplasmon regime to a strong dissipation with large spectral noise. Furthermore, we find a low-lying resonance peak as indicator of the pre-scission stage of the electron cloud.
