Dynamic coexistence of various configurations: clusters vs.nuclei

TL;DR

This paper explores how energy shell effects cause dynamic coexistence of different configurations in metallic clusters and atomic nuclei, highlighting quantum oscillations as a key factor in their structure and energy spectra.

Contribution

It introduces the concept of dynamic quantum coexistence of configurations in clusters and nuclei, emphasizing the role of quantum oscillations beyond static effects.

Findings

Energy shells influence structure and spectra of clusters and nuclei.

Quantum oscillations lead to coexistence of configurations.

Experimental data supports dynamic coexistence phenomena.

Abstract

The presence of energy shells in metallic clusters and atomic nuclei leads to a peculiar relation between the number of particles N and the structure, and this leads to a strong correlation between the energy spectrum and N. An analysis of experimental data leads to the conclusion that, in addition to the static Jahn-Teller effect, the dynamic effect leading to the quantum coexistence of different configurations (quantum oscillations) plays an important role. Such suggested coexistence is an essential feature of clusters as well as nuclei, both finite Fermi systems.
